Stamping elbow material classification: Stamping elbow materials such as carbon steel, stainless steel, alloy steel materials. Carbon steel stamping elbow is cheap, usage. The alloy steel elbow is used on the special place. (divided into ordinary stainless steel, austenitic stainless steel - ferritic/bipolar type martensite stainless steel body and precipitation hardening stainless steel stainless steel.) Stainless steel stamping elbow from carbon steel elbow is the main material is different, its chemical composition can keep the elbow surface for a long time will not rust, not easy to corrode. Stainless steel to rust and corrosion resistance as the main features, and at least 10.5% chromium content, carbon content does not exceed 1.2% of the largest steel.
