Product Description

Product Description

1: 4130 steel introduction
AISI 4130 alloy steel is a medium carbon, low alloy steel in ASTM A29 standard. ASTM 4140 steel is also commonly referred to as a chromoly steel, or chrome moly steel, containing nominally 0.28-0.33% Carbon, 0.8-1.1% Chromium and 0.15-0.25% Molybdenum. It is similar to 4140 steel which has a higher carbon level (0.28-0.33%), giving 4130 material improved weldability, at the expense of through thickness strength. With the proper heat treatment it is also readily machined. Annealing ASTM 4130 alloy steel offers excellent ductility. AISI 4130 steel is usually supplied as round bar commonly in the hardened and tempered condition.

Detailed Photos

AISI 4130 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance. Not many grades can match the versatility and usefulness of 4130.
