    Weathering steel, that is, atmospheric corrosion resistant steel, is a series of low-alloy steel between ordinary steel and stainless steel, weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion-resistant elements, with the strength of high-quality steel, plastic duction, forming, welding, abrasion, high temperature, fatigue resistance, etc.

    Characteristic; The weather resistance is 2 8 times that of ordinary carbon steel, and the paintability is twice that of ordinary carbon steel. At the same time, it has the characteristics of rust resistance, corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used in steel structures that are exposed to the atmosphere for a long time, such as railways, vehicles, bridges, and towers.

    It is used in the manufacture of containers, railway vehicles, oil derricks, port buildings, oil production platforms and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment.

    It can be a manufacturer that can cut and shape according to customer drawings, natural rust and other businesses, as well as steel processing, engineering production, logistics and distribution.

    Our factory has a good cooperative relationship with major domestic steel mills. Main business; Weathering steel, rust steel plate, rust plate, red rust steel plate, rust red steel plate, landscape decoration red steel plate and other wholesale and retail, our company also provides customers with shear distribution and other services.

    Q245R is a boiler pressure vessel steel with a yield point of 245MPa. "Q" represents the yield point lead calendar of the steel, and the following number represents the yield point value, and the unit is MPA; If necessary, the steel number can be followed by a symbol indicating the quality grade and the method of deoxidation. The quality grade symbols are A, B, C, D.

    Deoxidation method symbol: f for boiling steel; b denotes semi-sedative steel; z represents sedative steel; tz stands for special calming steel.

    Steel: Steel is an iron-carbon alloy with a mass percentage of carbon between to.

    Collectively referred to as . The chemical composition of steel can vary greatly and contain only the element carbon.

    The steel is called carbon steel.

    carbon steel) or ordinary steel; In actual production, steel often contains different alloying elements according to different uses, such as: manganese, nickel, vanadium and so on. The application and research of steel has a long history, but until the invention of the Bayesr steelmaking method in the 19th century, the production of steel was a costly and inefficient work.

    Today, steel is one of the most used materials in the world due to its inexpensive, reliable properties, and is an indispensable ingredient in the construction, manufacturing and daily lives of people. It can be said that stupid radical steel is the material basis of the modern society.

    Q345R is a kind of alloy steel, the yield strength of this alloy steel has reached the main use is used in boilers and pressure vessels, its process performance, mechanical properties are very stable, belongs to a kind of low alloy steel. Q345R steel is widely used in boilers or oil industry, and can be made into liquefied gas tanks or LPG cylinders.

    According to the new classification of GB713-2008 steel plates for boilers and pressure vessels implemented on September 1, 2008, 16MNG and 16MN and 19MNG are merged into ordinary low-alloy steel, which is a commonly used steel for boilers and pressure vessels, and the Q345R process refers to the standard GB713-2008.

    Q - "Qu" is the first letter of Chinese pinyin. 345—Yield strength value. r: The first letter of "Rong" in Chinese pinyin.

    Q345R steel is a special plate for pressure vessels with a yield strength of 340MPa, which has good comprehensive mechanical properties and process properties. The phosphorus and sulfur content is slightly lower than that of low-alloy high-strength steel plate Q345 (16Mn) steel, in addition to the tensile strength and elongation requirements are higher than those of Q345 (16Mn) steel, and the impact toughness is also required. It is currently the most widely used and largest special steel plate for pressure vessels in China.

    1. The content of trace elements is different. The phosphorus and sulfur content of Q345R is slightly lower than that of Q345, a low-alloy high-strength steel plate; Q345r p,s; And Q345 p,s.

    2. The scope of application is different. Q345 has good comprehensive mechanical properties, acceptable low-temperature performance, good plasticity and weldability, and is used as a structure, mechanical parts, building structure, general metal structural parts, etc., which bear dynamic loads such as medium and low pressure containers, oil tanks, vehicles, cranes, mining machinery, power stations, bridges, etc.; The Q345R is the most widely used and the most widely used special steel plate for pressure vessels.

    Alloy steel. Its main use is a common material for boilers and pressure vessels. Q345R has good process performance and good comprehensive mechanics.

    It belongs to a special plate for pressure vessels. It is a low-alloy steel that has more tensile strength than Q345 steel.

    The requirements for elongation and other aspects are higher, in addition, it is also required to ensure its impact toughness. At present, it is one of the special steel plates for pressure vessels with the largest amount, the best sales volume and the most widely used in China. <

    Heheng is only gold steel. Its main use is a common material for boilers and pressure vessels. Q345R has good process performance and good comprehensive mechanical properties, it belongs to a special plate for pressure vessels.

    It is a low-alloy steel, which has higher requirements than Q345 steel in terms of tensile strength, elongation, etc., in addition, it also requires to ensure its impact toughness. It is one of the largest, best-selling and most widely used special steel plates for pressure vessels in China, and is now widely used in chemical, power station, petroleum, boiler and other industries.

    Q345R is the material in GB 713-2008 "Steel Plate for Boiler and Press", which replaces the original 16MNG and 16MNR, is an ordinary low-alloy steel, and is a common steel for boiler pressure capacity vessels, Q stands for yield strength.

    345 is the yield strength value and r is the container. For specific reference, please refer to the GB713-2008 standard.

    1. The definitions are different.

    Q235: Q235 ordinary carbon structural steel is also known as A3 steel.

    Ordinary carbon structural steel plate is a kind of steel material.

    Q represents the yield limit of this material, and the subsequent 235 refers to the yield value of this material, which is about 235MPa. And with the increase of the thickness of the material and its yield value decreases, due to the moderate carbon content, good comprehensive performance, strength, plasticity and welding and other properties are better matched, the most widely used.

    Q345: Q345 is a type of steel. It is a kind of low-alloy steel.

    2. The application is different.

    Q235: Widely used in architectural and engineering structures. It is used to make steel bars or build factory frames, high-voltage transmission towers, bridges, vehicles, boilers, containers, ships, etc., and is also widely used as mechanical parts with low performance requirements.

    C and D grade steel can also be used as some professional steel.

    It can be used for all kinds of mold handles as well as other unimportant mold parts. Q235 steel is used.

    As a punch material, it is used directly without tempering after quenching, and the hardness is 36 40HRC, which solves the phenomenon of punch fragmentation in use.

    Q345: Widely used in bridges, vehicles, ships, buildings, pressure vessels, special equipment.

    Wait. <>

    3. The performance is different.

    Q235: Due to the moderate carbon content, the comprehensive performance is better, and the strength, plasticity and welding properties are well matched, and the most widely used.

    Q345: Q345 decreases the yield value of the material as its thickness increases. And the domestic one may be less than 345, so in the mechanical design.

    The strength must be less than 345, otherwise there will be problems.
