SA871 Type II Gr.65

ASME SA871 Type II Grade 65 Weathering Steel

Grade: ASME SA871 Type II Grade 65 Steel plate
Standard: ASME
Thickness: 6-420mm
Width: 1600-4200mm
Length: 6000-12000mm

ASME SA871 Type II Grade 65 Introduction
ASME SA871 Type II Grade 65 can be exposed to the atmosphere without painting. It begins to rust in the same way as ordinary steel. But soon the alloying elements in it cause a protective surface layer of fine-textured rust to form, thereby suppressing corrosion rate.
ASME SA871 Type II Grade 65 exhibits a better resistance to corrosion than ordinary steel, it has smallest alloy elements which doesnot like stainless steel and it is cheaper than stainless.
In this way, ASME SA871 Type II Grade 65 helps to reduce life-cycle costs and environment burdens in a wide range of applications. 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.

  • Railway train, dining car, reefer car, etc
  • Stamping piece and decoration piece
  • Transportation manufacturing
  • Facades, wall cladding
  • Architectural roof
  • Landscape
  • Sculpture
  • Tanks
ASME SA871 Type II Grade 65 Service
These plates are in a variety of sizes and thicknesses, and are 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.
