SA871 Type II Gr.60

ASME SA871 Type II Grade 60 Weathering Steel

Grade: ASME SA871 Type II Grade 60 Steel plate
Standard: ASME
Thickness: 6-420mm
Width: 1600-4200mm
Length: 6000-12000mm

ASME SA871 Type II Grade 60 Introduction
ASME SA871 Type II Grade 60 is one kind of high strength low alloy steel plate, and mainly used in pipe structure and structure parts. To meet the mechanical properties requirements, there are two grade: Grade 60 and Grade 65. Also can be hot rolled, Normalizing, or quenched and tempered treatment.
It is a copper chromium alloy steel – this alloy displays a greater level of resistance to atmospheric weathering when compared to other unalloyed steels. Its chemical composition promotes the early formation of an adhering protective layer of rust when exposed to the elements.
According to A6/A6M Standard requirement, structural steel impacts test sampling method according to A673/673M. Steel should be used in fine grain production process.

ASME SA871 Type II Grade 60 Application
The mechanical characteristics and the resistance to atmospheric corrosion make this steel, the best product for the fabrication of agricultural vans and railway wagons, structures of bridges, water pipes, fans, chimneys and boilers.
The material forms its own protective layer when exposed to atmospheric elements. Essentially, the top layer corrodes that then protects the steel beneath it. The natural finish does not normally require any form of maintenance such as painting, which makes the material a highly cost effective alternative to other structural steels.
Also is used for construction of tanks, containers, bridges, frame structures, vehicles, etc. with the request of welded, bolted, etc.

ASME SA871 Type II Grade 60 Service
These plates in a variety of sizes and thicknesses, and is available as ex–stock or directly shipped from the mill. As with all our steels, our plates come with mill test certification, stampings and fully traceable. We can arrange for a variety of tests to be performed on the material if specified.
