SUS304 stainless steel is a common material in stainless steel, density of 7.93g / cm, also known as 18 / 8 stainless steel in the industry.  High temperature resistance 800 ℃, with good processing performance, high toughness characteristics, widely used in industry and furniture decoration industry and food and medical industry.  Common labeling methods in the market include 06Cr19Ni10 and SUS304, among which 06Cr19Ni10 is generally referred to as national standard production, 304 is generally referred to as ASTM standard production, and SUS 304 is used as daily standard production.  304 is a universal stainless steel, which is widely used to make equipment and parts requiring good comprehensive performance ( corrosion resistance and molding ).  In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18 chromium, more than 8 nickel content.  304 stainless steel is a brand of stainless steel produced in accordance with ASTM standards in the United States.

SUS316 stainless steel, 18cr-12ni-2.5mo has good corrosion resistance, atmospheric corrosion resistance and high temperature strength due to the addition of Mo, which can be used under harsh conditions.  Good processing hardening ( non-magnetic ).  Seawater equipment, chemistry, dyes, paper making, oxalic acid, fertilizer and other production equipment;  Photography, food industry, coastal facilities, ropes, CD rods, bolts, nuts.  Chemical composition of 316 stainless steel: C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.035, S ≤ 0.03, Ni: 10.0-14.0, Cr: 16.0-18.5, Mo: 2.0-3.0.  316 stainless steel mechanical properties, tensile strength ( Mpa ) 620 MIN, yield strength ( Mpa ) 310 MIN, elongation ( ) 30min, area reduction ( ) 40min, 316 stainless steel density 8.03g / cm3, austenitic stainless steel generally use this value.
