304 Stainless Steel
For 304 stainless steel, the Ni element in its composition is very important, directly determines the corrosion resistance of 304 stainless steel and its value.
The most important elements in 304 are Ni and Cr, but they are not limited to these two elements. Specific requirements are specified by product standards. Industry common judgment situation that as long as the Ni content is greater than 8%, Cr content is greater than 18%, it can be considered 304 stainless steel. This is why the industry will call this type of stainless steel 18/8 stainless steel. In fact, the relevant product standards have very clear provisions for 304, and these product standards for different shapes of stainless steel and there are some differences. Below are some common product standards and tests.
To determine whether a material is 304 stainless steel, must meet the requirements of each element in the product standard, as long as there is a does not meet, can not be called 304 stainless steel.
Each standard actually has different requirements for 304, so to determine whether a material is 304, the accurate expression should say whether it meets the requirements of 304 in a product standard: No. Standard/304 C Mn P S Si Cr Ni N Cu 1 ASTM A276/A276M-15 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 2 ASTM A959-11 0.07 2.00 0.045 0.030 1.00 17.5-19.5 8.0-11.0 3 ASTM A240/A240M-15a 0.07 2.00 0.045 0.030 0.75 17.5-19.5 8.0-10.5 4 ASTM A182/A182M-15 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 0.1 5 ASTM A193/A193M-15 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 6 ASTM A269/A269M-15 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 7 ASTM A312/A312M-15a 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 8 ASTM A320/A320M-15a 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 9 ASTM A403/A403M-15 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 10 ASTM A493-09(2013) 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-10.5 0.10 1.00 11 ASTM A554-15a(MT-304) 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0 12 JIS G4303:2012 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-10.5 13 JIS G4304:2012 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-10.5 14 JIS G4305:2012 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-10.5 15 GB/T 20878-2007 0.08 2.00 0.045 0.030 1.00 18.0-20.0 8.0-11.0
Stainless Steel Sheet
A stainless steel sheet is a type of sheet metal made from an alloy of steel and chromium. Though the thickness of a ss plate can vary, it is generally thicker than metal leaf or foil, but thinner than a metal plate.
stainless steel plate is available in Type 304 and Type 316. Type 304 can be easily roll-formed or bent, and its excellent corrosion resistance and weldability make it one of the most popular grades. Type 316 is a high corrosion resistance alloy, providing greater resistance to pitting-type corrosion. Typical uses for Type 316 include marine, chemical, paper, textile, and food service applications, such as a stainless steel backsplash. Our stainless sheet is dual certified 316/316L, which helps prevent corrosion after welding.
