304 stainless steel: 304 stainless steel is the most common type of steel, as a wide range of USES of steel, with good corrosion resistance, heat resistance, low temperature strength and mechanical characteristics;
Stamping, bending and other thermal processing, no heat treatment hardening phenomenon (no magnetic, then with temperature -196℃ ~ 800℃).
316 stainless steel: 18cr-12ni-2.5Mo contains molybdenum (Mo) which is not made of 304 material,316′s anticorrosion is better than 304.
Molybdenum can further improve the corrosion of the atmosphere, especially the corrosion of the atmosphere containing chloride, is next to 304, the second most widely used steel, the main characteristics of acid and alkali resistance, resistance to high temperature than 304, and 316 stainless steel has a significant feature, is basically no thermal expansion and cold shrinkage phenomenon.
Major component difference
304 stainless steel and 316 stainless steel both contain about 16~18% chromium, but 304 stainless steel has an average of 9% nickel and 316 stainless steel has an average of 12% nickel.
Nickel can improve high temperature durability, mechanical properties and oxidation resistance in metal materials.
Therefore, the amount of nickel in the material directly affects the comprehensive properties of the material.
304 (0Cr18Ni9) stainless steel is austenitic stainless steel, can not be strengthened by heat treatment, can not be quenched like carbon steel, there is no magnetic.
304 of all kinds of mechanical properties are relatively excellent, with a considerable corrosion resistance, high temperature resistance, as rust resistant heat resistant steel is the most widely used.
316(0Cr17Ni12Mo2) contains molybdenum (Mo), which is not made of 304 material.
Molybdenum can further improve the corrosion of atmosphere, especially the corrosion of chloride atmosphere.
