Steelo Fabrica is a major producer and supplier of ASTM A638 Gr.660 type 2 Forged bar.
ASTM A638 Gr.660 type 2 Forged Bar/Rod:
ASTM A638 Gr.660 type 2 Forged Bar is work under high temperature bolting with co-efficient expansion similar to Austenitic Stainless Steel. Comparable to Incoloy, ASTM A638 Gr.660 type 2 Forged Bar can be age-hardened with both oil quench and liquid quench conditions.
Unlike other precipitation hardening steels, this ASTM A638 Gr.660 type 2 Forged Bars requires Stress Rupture Testing with less rupture. Working at High temperature and low-stress applications, good corrosion resistance at high temperatures is some of the most A638 Stainless Steel Properties.
Table of Content
Grade 660 or known as A286, seems to be an iron-based nickel-containing superalloy. But since the compound of ASTM A638 Gr.660 type 2 contains a high grouping of nickel; the metal is worked as a nickel-based alloy instead of a hardened steel. In addition to having high strength, the ASTM A638 Gr.660 type 2 Rod also exhibits superior corrosion resistance properties up to a temperature of 1300°F. Although, in the presence of aqueous media, the Gr 660 Rod is known to exhibit moderate corrosion resistance properties.
Properties:
This particular standard covers the inclusion of various elements in the chemical composition of the bars and rods. And the specification also has prerequisites that the Grade 660 bolts conform to other properties such as elongation, hardness, yield, and tensile strength.
Application:
The classification of this alloy is a high-strength, yet, the applications of the ASTM A638 Gr.660 type 2 Forged Rod are suited for a low-pressure application where the temperature is elevated. Ideally, the use of ASTM A638 Gr.660 type 2 Forged Bar is commonly seen in valve flanges or pressure vessels. Some of the other applications are:
