Bearing steel standards for the Astm system
Are you interested in bearing steels supplied by ASTM standards? from the supplier company AvecGlob? Here you will find interesting information on this topic.
General information
Bearings of foreign production are delivered in accordance with the requirements of the ASTM A295 specification. This specification covers all grades of high-carbon steels used for the production of bearings. Materials must comply with the chemical compositions specified herein, as well as the physical dimensions and form agreed between the manufacturer and the buyer.
The steels must exhibit a fine grain size of the fracture upon quenching from normal austenitic temperatures. Decarburization and surface defects should not exceed the limits specified here. When annealing is specified in the order, the steel must meet the requirements of hardness and have a fully spheroidized microstructure, which is accordingly evaluated in the form of carbide dimensions, carbide network and lamillar composition.
Marking of such steels is steel 52100, steel 52100 Grade2, steel 440C.
Supplier — AvekGlob Company — offers at a reasonable price from the manufacturer a diverse range of bearing steels that meet the technical requirements of the ASTM A295 standard. The supplier guarantees the timely delivery of products to any address specified by the consumer.
Application area
This specification refers to high-carbon structural steel, which is used in the manufacture of sliding bearings. If additional requirements are optional, they must be specified in the order.
