Soft (R) steel wire is subjected to bright heat treatment or pickling or similar treatment after heat treatment. b.The lightly drawn (Q) wire is subjected to a small degree of cold drawing after heat treatment.

As a versatile steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; Good hot workability such as stamping and bending, no heat treatment hardening phenomenon (non-magnetic, use temperature -196 800). Household goods such as tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, mufflers, moldings), medical appliances, building materials, chemicals, food industry, agriculture, ship parts.

There is a previous know!

Stainless steel profile SUS304 angle, cold brushed, hexagonal steel.

304 stainless steel is a common material in stainless steel, with a density of g cm3, which is also called 18 8 stainless steel in the industry. High temperature resistance 800, with good processing performance, high toughness characteristics, widely used in industry, furniture decoration industry and food and medical industry.

1.The common labeling methods on the market include 0Cr18Ni9 and SUS304, of which 0Cr18Ni9 generally represents the national standard production, 304 generally represents the ASTM standard production, and SUS 304 represents the Japanese standard production.

It is a general-purpose stainless steel, which is widely used to make equipment and parts that require good comprehensive performance, in order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium and more than 8% nickel content. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.

The most important elements are Ni and CR, but they are not limited to these two elements. The specific requirements are specified by the product standard. The common judgment situation in the industry is that as long as the Ni content is greater than 8% and the CR content is greater than 18%, it can be regarded as 304 stainless steel.

4.This is also the reason why the industry will call this kind of stainless steel 18 8 stainless steel, in fact, the relevant product standards have very clear provisions for 304, and these product standards have some differences for different shapes of stainless steel.

Stainless steel is widely used in curtain walls, side walls, roofs and other architectural purposes, but in the highly aggressive industrial or marine atmosphere, it is best to use 316 stainless steel, stainless steel sliding doors, people have fully recognized the advantages of using stainless steel in structural applications.

304 is equivalent to 06Cr19Ni10 stainless steel (GB T 20878-2007) in China.

Although this kind of stainless steel is very common in China, however.

The title of "304 stainless steel" comes from the United States. Many people think that 304 stainless steel is a type of name in Japan, but strictly speaking, the official name for 304 stainless steel in Japan is "SUS304". There are three common labeling methods on the market: 06Cr19Ni10, 304 and SUS304, of which 06Cr19Ni10 generally indicates the production of national standard standards, 304 generally represents ASTM standard production, and SUS304 indicates Japanese standard production.

304 stainless steel is a very common stainless steel, also known as 18 8 stainless steel in the industry, with high corrosion resistance and good processing performance, so it is widely used in industrial and furniture decoration industry and food and medical industry, such as: some high-end stainless steel tableware, bathroom kitchen utensils.

304 is a versatile stainless steel that is widely used in equipment and parts that require good overall properties (corrosion resistance and formability).

304 stainless steel is a common material in stainless steel, with a density of:

G cm3, also known as 18 8 stainless steel in the industry.

High temperature resistance of 800 degrees, with good processing performance and high toughness, it is widely used in industry, furniture decoration industry and food and medical industry.

The number of stainless steel material Stainless steel is not really never embroidered 304 is not a big problem in the basic bathroom.

JS304 is a Japanese expression.

SUS304 indicates that it is the American statement.

But they are all stainless steel made of 304 material, and there is not much difference in material.

Don't thank me, I'm a professional in stainless steel.

SUS is a Japanese material standard, and 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard. 304 is equivalent to China's (06CR19NI10) stainless steel, and Japan also quoted the name of the United States, calling it: SUS304.

Due to its high nickel content and austenitic single-phase structure at room temperature, it has high corrosion resistance compared with CR13 stainless steel, high plasticity and toughness at low temperature, room temperature and high temperature, as well as good cold work forming and weldability.

However, the strength at room temperature is low, the intergranular corrosion and stress corrosion tendency are large, and the machinability is poor. Austenite has no phase change when heated, so it cannot be strengthened by heat treatment. Improving the corrosion resistance of steel can only be done by heat treatment.

SUS304 refers to 304 stainless steel.

SUS304 i.e. 18 8 stainless steel. The GB grade is 0Cr18Ni9 (new standard 06Cr19Ni10). SUS304 is a Japanese JIS standard material, which is a Japanese SUS series austenitic stainless steel.

It is equivalent to 0cr18ni9 in China and 304 in the United States.

304 stainless steel has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, no heat treatment hardening, and no magnetism.

304 stainless steel is widely used in equipment and parts for corrosion resistance and formability due to its good heat resistance. At present, 304 stainless steel has been widely used in food, chemical, atomic energy and other industrial equipment and decoration fields, as well as household goods, cabinets, indoor pipelines, water heaters, boilers, bathtubs, auto parts, medical appliances, building materials, chemicals, food industry, agriculture, ship parts.

That is, it is authentic stainless steel, which is not easy to rust, and there are 302 ones, understand?

SUS304 is a material developed on the basis of 302, with a performance class of 302, but the corrosion resistance is better than that of 302, and it has good corrosion resistance and cold working stamping performance. It has strong corrosion resistance to oxidizing acids. It has 1 certain corrosion resistance to alkali solution and most organic acids and inorganic acids, good low temperature performance, and good strength, elongation and section shrinkage under -180 degree conditions.

It can be used for welding parts with thin cross-sectional dimensions, and it is a stainless steel with a large amount of application and a wide range of use. General-purpose oxidation-resistant steel that can withstand repeated heating up to 870 degrees Celsius. For more information, please consult the Shanghai Gangze team.
