不銹鋼1Cr17執(zhí)行標(biāo)準(zhǔn):GB/T 1220-1992
1Cr17不銹鋼抗拉強(qiáng)度大于450,屈服強(qiáng)度大于205,HBS小于183(數(shù)據(jù)為經(jīng)退火處理態(tài))。1Cr17不銹鋼常用作建筑裝飾,重油燃燒器零件等。430LX在430鋼中添加Ti或Nb、降低C含量,改善了加工性能的和焊接性能。用于熱水罐、供熱水系統(tǒng)、衛(wèi)生器具、家庭用耐用器具、自行車(chē)飛輪等。1cr17不銹鋼,鋼+12%以上的鉻可以防止自然因素所造成的氧化,稱(chēng)之為不銹鋼,在JIS的代號(hào)為430號(hào),因此又稱(chēng)為430不銹鋼。但1cr17不銹鋼無(wú)法抵抗空氣中的化學(xué)物質(zhì)所造成的氧化,因空氣中的酸性化學(xué)物質(zhì)愈來(lái)愈多,所以1cr17不銹鋼常使用一段時(shí)間后,仍會(huì)因非自然因素而有氧化(生銹) 的情況。
