Productomschrijving

DIN 1.2787 AISI 431 ESR Stainless Steel Round Bars for Glass Moulds

Premium ESR 431 stainless steel round bars specifically engineered for glass mold manufacturing. Available in prehardened or soft annealed states with rough peeled surface finish.

New Generation for Glass Molds Manufacturing

431 mod. represents a special improved grade derived from 1.4057, featuring ESR (Electro-Slag Remelted) technology that delivers longer mold life through extra fine microstructure.

Material Characteristics

AISI 431 is a high chromium-low nickel martensitic stainless steel with excellent hardenability, high strength, and good corrosion resistance. Typically supplied hardened and tempered in the tensile range 850-1000 MPa.

Excellent corrosion resistance in atmospheric environments
Good resistance to mild marine and industrial atmospheres
Resistant to organic materials, nitric acid, and petroleum products
High tensile and yield strength with excellent toughness
Capable of through hardening up to Rc44
Responds well to nitriding processes

Available Sizes & Finishes

Stocked sizes range from 6.35mm to 260mm diameter. Available finishes include peeled, cold drawn, turned and polished, and centreless ground.

International Specifications

Country	Standard	Designation
Australia	AS 2837-1986	431
Germany	W.Nr 1.4057	X20CrNi17 2
Great Britain	BS970 Part3 1991	431S29
Japan	JIS G4303	SuS 431
USA	ASTM A276-98b	431

Typical Applications

Glass molds, aircraft components, bolts and nuts, fasteners, pump shafts, propeller shafts, studs, and valve parts. Material is magnetic in all conditions.

Important Note: Tempering within the range 370°C - 565°C should be avoided due to significant drop in impact properties. For optimum corrosion resistance, ensure surfaces are free of scale and foreign particles, and consider passivation for finished parts.
