| titleOfInvention | High tempering parameter SR embrittlement resistant cryogenic nickel steel and manufacture method thereof |
| abstract | A high tempering parameter SR embrittlement resistant cryogenic nickel steel and a manufacture method thereof. The nickel steel comprises, by weight, 0.025%-0.060% of C, Si no more than 0.15%, 0.45%-0.85% of Mn, P no more than 0.012%, S no more than 0.0020%, 0.10%-0.40% of Cu, 2.80%-3.80% of Ni, 0.10%-0.30% of Cr, 0.05%-0.30% of Mo, 0.040%-0.070% of Als, 0.006%-0.012% of Ti, 0.008%-0.025% of Nb, N no more than 0.0040%, 0.001%-0.003% of Ca, residual iron and unavoidable inclusions. According to optimized controlled rolling and a normalizing plus tempering technology, the nickel steel gains extremely high ultralow temperature toughness, excellent HIC / SCC resistance, weldability and bearing capacity of high heat input welding; besides, the nickel steel has excellent high tempering parameter SR embrittlement resistance characteristic, and is especially suitable for manufacture of large-scale LPG low temperature storage tank, low temperature storage tank for ship and large-scale steel structure for ice ocean and polar region. |
