Duplex Steel Fastners

Duplex steels are becoming more popular in the fastener business for a variety of reasons, including increased strength – which helps with weight savings – and improved corrosion resistance, particularly in terms of stress corrosion cracking. The duplex was developed to achieve a balance between the austenitic and ferritic types of conventional steels, which provides a number of benefits in fastening, including increased structural strength, enhanced weldability, good toughness, and improved stress corrosion cracking resistance. Duplex stainless steel's resistance to stress corrosion cracking, in particular, is a true hallmark, while other stainless steel struggles in this area. These Duplex steel fasteners are used widely in industrial fields, mechanical works, and many more. Duplex Steel Fasteners are constructed from an alloy that has a high content of chromium and low to moderate content of nickel.Specification For Duplex Steel FastenersSpecifications:- ASTM A479/ A479, ASME S A479 / A479Standard:- IS, ANSI, ASTM DIN, ISO, JIS, GB, ASME, BS, UNISize:- M3 – M56 | 3/6? to 2? | Custom SizesLength:- 3 mm to 200 mmBolts:- ANSI B18.2.1, DIN 931/ 933Bolts Size Metric:- Dia: M10 – M110Length: 12 – 1200MMBolts Size Inch:- Dia: 1/2? – 4.0?Length: 1/2? – 52?Eye Bolts Metric Size:- Dia: M10 – M48Nut (DIA):- Metric: M6 – M110Inch: 1/4? – 4.5?Plain Washer (DIA):- Metric: M6 – M110Inch: 1/2? – 4.1/2?Value Added Services:- Cutting, Beveling, Polishing, Threading, Destructive, Non Destructive, Ultrasonic TestingInspection and Test Reports:- EN 10204 3.1, Mill Test Certificates, Chemical Reports, PMI Test Reports, Mechanical Reports, Third Party Inspection, NABL Approved Lab, Visual Inspection, Destructive Test and Non Destructive Test ReportsMarking:- Specification Grade Nominal Fasteners Sizes Fasteners Schedule or Pressure Manufacturing Method Heat Number Manufacturer’s Name or Custom Logo – on request Marked Fasteners Sample: ASTM A479 Fasteners HEAT NO.
