压力容器用钢板根据使用条件的不同，压力容器用钢板可分为碳素钢、低合金钢和不锈钢三大类。碳素钢具有成本低、强度适中的特点中心钢结构方案封面-secret，适用于中低温低压环境；低合金钢通过添加少量合金元素（如锰、铬、钼等），可显著提高强度和韧性，适合更高温度和压力的应用场景；而不锈钢则因其优异的耐腐蚀性能，广泛用于化工、食品等行业中涉及腐蚀性介质的压力容器。
为确保安全性，各国对压力容器用钢板制定了严格的标准，如中国的GB/T713《锅炉和压力容器用钢板》、美国的ASTMA516/A516M等。这些标准明确规定了钢板的化学成分、力学性能、厚度偏差及检验要求等内容。此外，钢板生产过程中还需经过探伤检测（如超声波、射线检测）以发现内部缺陷，从而保证材料质量。
随着工业技术的发展，高性能压力容器用钢板不断涌现，例如高强度细晶粒钢、耐氢脆钢等，满足了现代工业对极端工况的需求。未来，轻量化、高强韧性和多功能化的钢板将成为研发重点，推动压力容器行业的进一步发展。
