The storage tank is made of SPV4900; I wonder if anyone is familiar with this material
Thread Content
What is the equivalent material for SPV4900 in China?
Through a comparison of the composition and mechanical properties of 12MnNiVR and SPV490 steel, as well as welding tests and process evaluation of 12MnNiVR, corresponding welding process measures were developed. This demonstrated the feasibility of using domestically produced 12MnNiVR in place of SPV490 steel in large storage tanks. I’m not sure if your company is this material manufacturer – Shanghai Ruiyang, which specializes in container steel plates
I’m on a business trip away; I’ll take a look at it for you when I get back. Wuhan Panglong
SPV490 is a type of pressure vessel steel used in Japan. Did the person who posted this information accidentally include an extra “0”? Chemical composition (maximum values): C 0.18, Si 0.75, Mn 1.6, P 0.03, S 0.03. Mechanical properties (for thicknesses up to 50 mm, minimum values): yield strength of 490, tensile strength of 610–740. Impact strength at -10 degrees Celsius is greater than or equal to 47 J. Our company can supply sheets of this steel with a thickness of 8 mm or more. Wuhan Iron and Steel Group Panglong
