Superior hardness after heat treatment
Superior abrasive resistance,low friction coefficient
Superior limit of elasticity
Excellent impact toughness and fracture toughness
Excellent dimensional stability
Excellent anti-corrosion performance
Excellent cold,hot-working character
CLASSIFICATION AND APPLICATION
Bearing steel is a type of steel used in the field of fabricating the ball, pin roller, sleeve for antifriction bearing. and also measuring implements, cold-punching die, lead screw and precision components of diesel engine oil pump. Bearing steel is divided into high-carbon chromium bearing steel, carburizing bearing steel, stainless bearing steel, high temperature bearing steel, medium-carbon bearing steel.
Generally, condition of delivery is hot rolled+annealing, cold drawn+annealing.
PRODUCT DESCRIPTION
The alloy is usually produced by LF /EAF /IFF /VD followed by electroslag refining (ESR) if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black/bright in the annealed condition.
PRODUCT PROFILE & DIMENSIONS
Round bar / Wire rod (Diameter1): 5.50mm to 650mm
Square bar / Flat bar: 10mm to 800mm
Length: Fixed length or random length or based on the customer's special requirement.
