Duplex 2205 (S31803)
Duplex 2205 stainless steel (both ferritic and austenitic) is used extensively in applications that require good corrosion resistance and strength. At temperatures above 300°C, the brittle micro-constituents of this grade undergo precipitation, and at temperatures below -50°C the micro-constituents undergo ductile-to-brittle transition; hence this grade of stainless steel is not suitable for use at these temperatures.
Duplex S32750
Duplex 2507 is a super duplex stainless steel designed for applications which demand exceptional strength and corrosion resistance. Alloy 2507 has 25% chromium, 4% molybdenum, and 7% nickel. This high molybdenum, chromium and nitrogen content results in excellent resistance to chloride pitting and crevice corrosion attack and the duplex structure provides 2507 with exceptional resistance to chloride stress corrosion cracking.

Inconel 625
Inconel 625 is a material with excellent resistance to pitting, crevice and corrosion cracking. Inconel 625 is highly resistant in a wide range of organic and mineral acids. Good high temperature strength.
Inconel 825
Incoloy 825 is a nickel-iron-chromium alloy with additions of molybdenum and copper. This nickel steel alloy's chemical composition is designed to provide exceptional resistance to many corrosive environments.
These fasteners are available with us in various specifications including M12 TO M150 & 1/2" TO 6" length up to 1000 mm, moreover.
All thread is used for general purpose fastening for anything from an anchor bolt to a through bolt. A variety of grades and materials are available including stainless steel.
For high strength fasteners, one cannot simply substitute all thread rod for a headed bolt without a significant loss in strength. To learn why you may assume a tremendous amount of liability by making such a substitution Specification & Grades of mfg rods are as following table.
