AISI 4130 Fasteners

AISI 4130 Fasteners

AISI-SAE 4130 is a low alloy steel with chromium and molybdenum as its main strengthening elements. Alloy 4130 have a stable combination of high strength, toughness, weldability and machinability along with fatigue strength. AISI 4130 fasteners and bolting components finds manu applications across aerospace and oil field sectors.

Boltport offers made to order AISI 4130 fasteners in varieties of bolts, screws, stud bolts, studs, threaded rods, nuts, washers, pins & other bolting components, in hot forged condition. AISI 4130 fasteners are produced from premium bar stock or forging stock to various ASTM and International material specifications. AISI 4130 fasteners posseses high bolting strength and used for high temperature, high pressure applications. Automotive manufactures often refer to SAE Grade 4130 for ordering fasteners.
