: These are the cleanest non-alloy steels. They have very low amounts of phosphorus and sulfur. They react very well to heat treatments. Quality Classes for Alloy Steels
Helps global engineers find exact European equivalents for American ASTM/AISI or Japanese JIS grades. en 10020 pdf
EN 10020 mandates that steel grades must be divided into three major categories based on their chemical composition: non-alloy steels, stainless steels, and other alloy steels. The distinction is made by evaluating the specified ladle analysis against precise boundary values. 1. Non-Alloy Steels : These are the cleanest non-alloy steels
