904L Stainless steel gloss bar super 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 Stainless steel gloss 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. The coefficient of thermal expansion is small, and the team is only 60% ~ 70% of the chromium-nickel Olympic stenitic stainless steel, which is very suitable for thermal expansion, cold contraction and thermal circulation. The steel has good plasticity and toughness, and is suitable for drawing, rolling and stamping. In particular, stress corrosion resistance is the most excellent, in high chloride medium corrosion resistance is better than ordinary ferrite stainless steel and austenitic stainless steel, generally do not produce chloride stress corrosion rupture.

441 Stainless steel gloss 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 Stainless steel gloss 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 Stainless steel gloss 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

420J1 Stainless steel gloss bar features and scope of application: It has certain wear resistance and corrosion resistance, high hardness, its price is the 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.

410S Stainless steel gloss bar is a martensitic stainless steel. 410S(13Cr) has good corrosion resistance and machining performance, for general purpose steel, cutting tool steel. 410S is a kind of steel that improves the corrosion resistance and formability of 410 steel.

409L Stainless steel gloss bar ASTM standerd 2mm 3mm .409L stainless steel has excellent corrosion resistance, suitable for extending the life of the car and the lightweight of the car, and as a recyclable environmental protection material.

430 Stainless steel gloss bar, known as "stainless steel" in our stainless steel industry, has good corrosion resistance and excellent thermal conductivity than austenitic stainless steel.Stainless steel is mainly used for building decoration, fuel burner parts, household appliances, household appliances parts.
