ASTM A519 4130 Alloy Steel Tubing

Date:2021-07-28

aisi/sae 4130 steel grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength up to around 315º c (600º f). it shows good overall combinations of strength, toughness and fatigue strength.

size range(mm):

out diameter:10-324mm

wall thickness:1-30mm

length:14000mm max
