304 NO.1 Stainless Steel Flat Bar 3mm is one of the most popular stainless steel cold rolled sheet products.304 stainless steel has excellent corrosion resistance and good resistance to intergranular corrosion. 304 stainless steel is the most widely used stainless steel, heat resistant steel. Used in food production equipment, general chemical equipment, nuclear energy, etc.

301 NO.1 Stainless Steel Flat Bar 3mm Good ductility, used for molding products. It can also be quickly hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength is better than 304 stainless steel, compared with 304, Cr and Ni content is low, after cold rolling with magnetic.

202 NO.1 Stainless Steel Flat Bar 3mm ，stainless steel patterned plate has strong corrosion resistance and can resist the corrosion of most acid and alkali media; The price is moderate, more economical and practical; Good processability, welding, cutting, stamping and so on.

201 NO.1 Stainless Steel Flat Bar 2mm 3mm 4mm with polishing no bubbles, no pinholes and other characteristics, is the production of a variety of watchcase, watchband cover quality materials.

904L 2B Stainless Steel Flat Bar austenitic stainless steel is a high alloyed austenitic stainless steel with very low carbon content. It has good corrosion resistance in dilute sulfuric acid and is designed for harsh corrosion conditions. With high chromium content and sufficient nickel content, the addition of copper makes it have strong acid resistance, especially to chloride gap corrosion and stress corrosion cracking has high resistance, not easy to appear corrosion spots and cracks, pitting corrosion resistance is slightly better than other steel types, with good processability and weldability, can be used in pressure vessels.

444 2B Stainless Steel Flat Bar，444 (00Cr18Mo2) is an ultra-low carbon nitrogen, containing 18% chromium and 2% molybdenum, high corrosion resistance of ferritic stainless steel. The yield strength of 444 is equivalent to 1.5 times that of carbon steel and 6 times that of FRP. It has outstanding advantages in earthquake resistance, snow resistance, wind pressure resistance and impact resistance. SUS444 ferritic stainless steel has high thermal conductivity, about 130% ~ 150% of chromium-nickel austenitic stainless steel, which is very suitable for heat exchange purposes.

441 2B Stainless Steel Flat Bar，441 is made of stainless steel. Resistant to air, steam, water and other weak corrosion media or with stainless steel called stainless steel; And the chemical corrosion medium (acid, alkali, salt and other chemical erosion) corrosion of steel called acid resistant steel. Due to the difference in the chemical composition of the two and their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical media corrosion, and acid resistant steel is generally rust free.

439 2B Stainless Steel Flat Bar 439 steel is to reduce the content of C on the basis of ordinary ferrite material (430), while adding Ti and other stabilizing elements, so that the resistance to intergranular corrosion, formability and weldability of the steel are improved. Compared with 304 steel, although the elongation is lower (about 30%), but the strength, corrosion resistance is equivalent, and corrosion resistance is better than 200 series materials.

420J2 2B Stainless Steel Flat Bar has certain wear resistance and corrosion resistance, high hardness, its price is a lower class of stainless steel ball, suitable for the common requirements of stainless steel working environment. Suitable for all kinds of precision machinery, bearings, electrical, equipment, instruments, meters, transportation vehicles, household appliances, etc. It is mainly used to make parts that are resistant to atmospheric, water vapor, water and oxidizing acid corrosion
