Audited Supplier AISI 4140 is Chrome Moly High Tensile Steel, according to the standard of ASTM A29 / A29M.
AISI 4140 bearing ring forgings offer good balance on stength, toughness and wear resistance and etc.
Our raw material for AISI 4140 ring forgings require EAF+LF+VD melting methods.
With the heat treatment for AISI 410 ring forgings, normally we using normalized+Quenched+Tempered or Quenched and Tempered to meet the technical requirements of customers.
Mechanical Properties of AISI 4140 after Heat treatment:
Tensile Strength: 130 KSI Min (896 N/mm²)
Yield Strength: 110 KSI Min (758 N/mm²)
Elongation: 13%
Red of Area: 30%
There are three miils: ø 1600mm, ø 3000mm, ø 5000mm ring roller mills, forging workshops.
With machining, heat treatment workshops and experienced workers, enable our company manufactures all kinds of ring forgings, seamless rolled ring products to support our customer worldwide.
We supply AISI 4140 Forged Rings / Forgings pre-turned Ring Parts as per certificate EN10204-3.1.
Ultransonica Testing will be as per standard as ASTM A388 or EN10228-3, 100% UT will be done for AISI 4140 Bearing Ring Forgings.
