ASTM A519 4130 tube is a alloy steel grade of steel that contains chromium and molybdenum, and as a result this grade is often referred to as chromoly steel, chrome-moly, CrMo, CRMO, CR-MOLY. ASTM A519 4130 tubes are produced in mechanical tubing, either hot finihshed or cold finished. A519 4130 tubes can be furnished in the following shapes: round, square, rectangular and special sections.

1inch OD Sch80 walll ASTM A519 4130 stel tubes show excellent strength to weight ratio and is considerably stronger and harder than standard carbon steels.

ASTM A519 4130 material is not as easily weldable compared to other materials such as BS4 T45 to BS5 T100 or 15CDV6 (1.7734) as it requires pre and post weld heat treatment to avoid cold cracking. It is also unadvisable to weld Chromoly to other carbon steel grades due to the differences in chemical construction. A519 4130 steel tubes can be achieved but particular attention to vital stress areas and heat affected zones most be made.
