430 stainless steel
Iron +12% or more of chromium can prevent oxidation caused by natural factors, called stainless steel, codenamed 430 in jis, so it is also called 430 stainless steel. However, 430 stainless steel is not resistant to oxidation caused by chemicals in the air, and it still rusts due to unnatural factors.
18-8 stainless steel
Its alias 304 stainless steel name or more loud, iron +18% chromium +8% nickel, can resist chemical oxidation, this stainless steel in the jis code is No. 304, so it is also known as 304 stainless steel. With high temperature resistance of 800 degrees, it has the characteristics of good processing performance and high toughness.
18-10 stainless steel
Environmental pollution causes more and more chemical components in the air. Some areas with more serious pollution will have rust in 304; so some high-grade products will be made of 10% nickel to make them more durable and resistant. This stainless steel is called 18-10 stainless steel.
