Refers to low-alloy steel forgings. It belongs to carbon steel. According to the regulations, the materials starting with A182 are stainless steel.

This kind of material requires that the carbon content of carbon steel is less than that, and it cannot contain other alloying elements except for iron, carbon and a certain amount of impurities such as silicon and manganese. Normally, the carbon content of industrial carbon steel is general, and the performance of carbon steel mainly depends on its carbon content. In production and life, carbon steel is used at the earliest, its cost is also low, the performance range is wider, and the amount is the largest.

Significance1. Make full use of China's rich resources and take the road of "independence and self-reliance".

China's ordinary low-alloy steel is an independent low-alloy steel system developed by making full use of China's rich resources and getting rid of the shackles of nickel and chromium. Nowadays, China has not only smelted high-quality low-alloy steel without nickel and chromium, but also created a lot of new steel grades with excellent performance by using China's rich resources, and created a new situation in the development of steel grades.

2. It has effectively supported national defense construction.

Due to the high strength and good comprehensive performance of ordinary low-alloy steel, the equipment made of it has the characteristics of lightness, fast speed and good performance, and has played a great role in national defense construction.

3. It has effectively promoted the juice revolution, process revolution and product revolution in various industrial sectors.

a 182 grade f11 cl.1. It belongs to the American standard pearlite structure heat-resistant steel forgings, and the implementation standard: ASTM-A182 A182M-2017 "American Society for Testing and Materials Standards:

Forged or rolled alloy steel and stainless steel pipe flanges, forged pipe fittings, valves and parts for high temperatures".

a 182 grade f11 cl.1 of which represents Class 1 forgings, the specific chemical composition is as follows:

A182-F11 has high thermal strength (ΔB 440MPa) and oxidation resistance at high temperature, and has a certain ability to resist hydrogen corrosion. Due to the high content of Cr, C and other alloying elements in the steel, the hardening tendency of the steel is more obvious and the weldability is poor. Due to the addition of alloying elements such as CR and MO in low carbon steel, the comprehensive properties of steel are greatly improved.

For example, it has good high-temperature mechanical properties, high-temperature oxidation resistance, corrosion resistance, good toughness, process performance and weldability, so it is widely used in the manufacture of large-scale equipment with harsh and complex corrosive media such as petrochemical industry, coal conversion, nuclear power, steam turbine cylinder block, thermal power, etc.

It is commonly referred to as P11 material.
