Characteristics

AISI 5140 Alloy Steel  is medium carbon tempered steel, which is cold heading steel and easy to process, after proper heat treatment it can obtain a certain toughness, plasticty and abrasion resistance.

Applications

After tempering,it is used to manufacture mechanical parts that can bear medium load and moderate speed, such as steering knuckle of automobile, rear axle, gears, shafts, worm shafts, spline shafts and center sleeves on machine tools.

Delivery Time: 7-10 working days for steel in stock. 20-60 working days for direct production based on the quantity.
