Q235螺旋焊管規(guī)格
Q235螺旋管屬于碳素結(jié)構(gòu)鋼，主要原料為鐵水加廢鋼，鋼中硫、磷含量高于優(yōu)質(zhì)碳素結(jié)構(gòu)鋼，一般硫≤0.050%，磷≤0.045%。由原料帶入鋼中的其他合金元素含量，如鉻、鎳、銅一般不超過0.30%，按成分和性能要求，此類鋼的牌號由Q195，Q215A、B，Q235A、B、C、D，Q255A、B，Q275等鋼級表示。
注：“Q”是屈服的“屈”字的漢語拼音大寫字頭，其后數(shù)字為該牌號最小屈服點（σs）值，其后的符號是按照該鋼雜質(zhì)元素（硫、磷）含量由高到低并伴隨碳、錳元素的變化而分為A、B、C、D四等。
