类型

中厚板,固溶后除鳞交货。

较薄的板,厚度公差和表面更好。

圆板、环板、管板坯,按图纸切割。
厚度、宽度与长度公差
按标准供货时厚度、宽度、长度允许的偏差。要更严的公差,询价时写明。
ASTM B127、B162、B168、B409、B424、B443镍基合金板厚度负偏差 0.3 mm0.01 in允许超重 4 – 19.5 %
板按厚度采购,不按重量。任何一处低于规定厚度不超过 0.3 mm(0.01 in),修磨去表面缺陷的地方也一样;厚度 51 mm(2 in)及以下的板,正的一边按每批平均重量限制,见第一张表。
厚度 51 mm 及以下:每批平均重量允许超出名义重量的百分数

- 平直度适用于长 4.57 m(15 ft)以内的板,或更长板的任意 15 ft;长边不足 914 mm(36 in)时不超过 6.35 mm(¼ in)。短边算宽度,宽度方向不超过该尺寸对应的表值;一般不超过长边对应的表值。
- 钛板指厚 4.76 mm(3/16 in)及以上、宽 254 mm(10 in)以上;更窄的按扁棒(B348)。力学性能保证到厚 25 mm(1 in)。
铜镍、锆板的公差,询价时确认。
