S-express structural steel in s235jr, 235 is the lower limit of yield strength.
S235JR steel plate is a European standard non-alloy structural steel, that is, a carbon structural steel with a low carbon content, which is used for welding, bolting, and riveting structures.
Carbon structural steel, the carbon content is about 0.05% to 0.70%, and individual can be as high as 0.90%. It can be divided into ordinary carbon structural steel and high-quality carbon structural steel.
Standard implemented by S235JR: EN10025;
S235JR delivery status: normalized, controlled;
S235JR flaw detection standard: 'one probe, two probes, three probes';
S235JR thickness can be done: Z15, Z25, Z35;
1.6, S235JR density: 7.85/cubic meter;
1.7. S235JR adjusted weight formula: thickness * width * length * 7.85;
