The chemical composition of stainless steel I-steel belongs to the general structure of rolled steel series, the main test index for C, Mn, P, S four items. According to different brands, the content varies, the general range is C<0.08%, Mn: 2.0, P<0.035%, S<0.03%.
When detecting the above chemical components, the commonly used standard inspection methods include GB223, JISG1211-1215, BS1837, BS19, and (Tip22536), respectively.
National standard: GB13296-97, GB/T14976-2002, GB/T14975-2002.
American standard: ASTM A312/A312M, ASTM A213/A213M, ASTM A269/A269M.
German standard: DIN 2462.
Other standards: Can be manufactured according to customer supplied standards.
Matters needing attention
Stainless steel I-steel is welded after the shear of stainless steel plate, so what problems should we pay attention to when welding I-steel?
1. Welding should be welding from the same direction, spot welding and then repair welding.
2. Welding should be according to the thickness of the stainless steel plate to choose the welding mode, a little thinner welding with argon arc welding, and a little thicker to use submerged arc welding, in order to welding can be welded through.
3. After welding is the straightening problem of I-steel, in the process of welding, because of the heat problem, will lead to stainless steel I-steel bending, it is necessary to use equipment for straightening.
The above three points are the problems that should be paid attention to when welding, I hope to help you.
