20高压锅炉管是属于优质碳素结构钢(GB/T699-1999),优质碳素结构钢是依靠调整含碳(C)量来改善钢的力学性能,因此,根据含碳量的高低,此类钢又可分为:
低碳钢--含碳量一般小于0.25%,如10、20钢等;
中碳钢--含碳量一般在0.25~0.60%之间,如35、45钢等;
高碳钢--含碳量一般大于0.60%。此类钢一般不用于制造钢管。
实际上,他们之间的含碳量并没有明显的界限。
此类钢产量较大,用途较广,一般多轧(锻)制成圆、方、扁等型材、板材和无缝钢管。主要用于制造一般结构及机械结构零、部件以及建筑结构件和输送流体用管道。根据使用要求,有时需热处理(正火或调质)后使用。
高压锅炉用无缝钢管(GB5310-1995)是用于制造高压及其以上压力的水管锅炉受热面用的优质碳素钢、合金钢和不锈耐热钢无缝钢管。
