Model Number: hot forged steel bar -31
Brand Name: Unite Steel
Key Specifications/Special Features:
Forged steel bars, Q+T 4137HIntroduction:4137H forged steel bars Q+T SAE 4137His an H-steel gradealloy steelCommonly called SAE 4137H Chromium-molybdenum steelSAE 4137H offers good ductility and shock resisting properties combined with resistance to wear
With these characteristics it is a popular high tensile engineering steel with a tensile of 850°-1000N/mm
At low temperatures it has reasonably good impact properties
Suitable for a variety of elevated temperature applications
For maximum wear and abrasion resistance the steel can be nitrided to give a shallow depth wear resistant case
Flame or induction hardening of 708M40T can give a case hardness of 50HRc or higher
