Durable In Use Stainless Steel Round Bars 410 444 Hot Rolled Alloy Od60mm
1. Introduction
400 Series - Ferritic and martensitic stainless steels
408- Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni.
409- The cheapest model (Anglo-American), usually used as an automobile exhaust pipe, is ferritic stainless steel (chromium steel).
410-martensite (high strength chromium steel), good wear resistance, poor corrosion resistance.
416- Sulfur is added to improve the processing properties of the material.
420-" tool grade "martensitic steel, similar to Brinell high chromium steel, the earliest stainless steel. Also used in surgical knives, can do very bright.
430-ferritic stainless steel for decorative purposes, e.g. car ornaments. Good molding, but poor temperature resistance and corrosion resistance.
440- High strength cutting steel, slightly higher carbon content, after proper heat treatment can obtain high yield strength, hardness can reach 58HRC, is one of the hardest stainless steel. The most common example is the "razor blade". There are three commonly used models :440A, 440B, 440C, and 440F(easy to process).
