High Strength Low Alloy Steel Round Bar Manufacturer In China 16mncr5 20mncr5
JIS/KSSPFC590 AISI/SAEGrade 50(345)Low Alloy Steel Bar EN10025
Low-alloy steel is relative to carbon steel. Low alloy steels are widely used for the production of pipes, automotive and aerospace bodies, railway lines and offshore and onshore structural engineering plates. High-strength low alloy steel is used in these areas due to its corrosion resistance properties.There are four major groups of low alloy steels which are normally used. These groups are (i) low carbon quenched and tempered steels, (ii) medium carbon ultra high strength steels, (iii) heat resistant chromium-molybdenum steels, and (iv) bearing steels.
