ASTM A 829 – Grade 4140/4142
Exactly the hardness and mechanical strength you need
Grade 4140 and Grade 4142 are quenching and tempering steels in accordance with American codes of practice for the mechanical-engineering and tool-making fields, with a defined hardness range, unlike steels in accordance with the American standard.
The strengths of Grade 4140 and Grade 4142 proprietary steels
- These two quenching and tempering steels in accordance with ASTM A829 are comparable to a 42CrMo4 as specified in EN 10083, Part 3.
- Above and beyond the applicable standard, these products are also tested for additional application-specific properties.
- We supply Grade 4140 and Grade 4142 entirely to meet your requirements, in various delivery states and with precisely defined hardness ranges, up to plate thicknesses of 300 mm.
- These steels convince users with their excellent cleanness and homogenous microstructure, precisely defined hardness and mechanical-strength range in delivery state. These assure low tool wear and good machinability.
