Instructions | 304 is a typical low-carbon austenitic stainless steel, corresponding to the domestic grade 0Cr18Ni9, the grade is on the basis of 302 to further reduce the carbon content of the obtained, with good processing molding and oxidation resistance, oxidation acid (such as nitric acid) has a strong corrosion resistance, alkali solution and most organic acids and inorganic acids also have a certain corrosion resistance. It has good welding performance. Austenitic stainless steel cannot be strengthened by heat treatment and can only be strengthened by work hardening. |
304 Good cold processing performance, bolts, screws can be cold heading molding, other products can also be bent, crimping, folding, deep drawing and other processing, hot processing performance can also be. | |
304 is widely used in standard parts, in addition to the production of national standard products, but also the production of some low-strength beacon products, a variety of enterprise standard products more production. | |
Selection suggestions: | |
Tensile strength of 500Mpa or 700Mpa above, with oxidation resistance, acid, alkali and salt corrosion resistance, while there is no magnetic requirements, recommended use. | |
Density | 7.85g/cm3 |
304 SAE AMS 5639J-2017 stainless steel wire surface bright, beautiful and durable, with good corrosion resistance, acid and alkali resistance, high temperature resistance, not easy to wear and aging and other characteristics. In addition, its toughness is good, high strength, easy to process and form.
