JIS G3125 SPA-H Weathering Steel

SPA-H is a kind of weathering steel. The steel grade adopts Japanese steel grade SPA-H. The deviation of its chemical composition, mechanical properties, thickness and width requires the implementation of Japanese standard JISG3125-2004 "High Weather Resistance Rolled Steel".

SPA-H Weathering Steel Mechanical properties:

Grade	Yield strength	Tensile strength	Elongation
SPA-H	≥355MPa	≥490MPa	≥15

SPA-H Weathering steel features:
Weathering steel SPA-H has good atmospheric corrosion resistance, and also has the characteristics of high temperature, abrasion, forming, fatigue, toughness, plastic extension, etc. It can be used bare, thinned or simplified for painting. SPA-H is rust-resistant, which can reduce the thickness and consumption of components, resist atmospheric corrosion and prolong life. It has the characteristics of saving labor and energy, benefiting component manufacturers and users.

SPA-H weathering steel is equivalent to Q345GNHL (09CuPCrNiA) in GB/T 4171, and is mostly used for container steel plates.
