異型管成分檢驗(yàn)標(biāo)準(zhǔn)
折疊是異型管表面形成的各種折線，這種缺陷往往貫穿整個(gè)產(chǎn)品的縱向。產(chǎn)生折疊的原因是由于偽劣廠家追求高效率，壓下量偏大，產(chǎn)生耳子，下一道軋制時(shí)就產(chǎn)生折疊，折疊的產(chǎn)品折彎后就會(huì)開(kāi)裂，鋼材的強(qiáng)度大下降。
偽劣異型管無(wú)金屬光澤，呈淡紅色或類(lèi)似生鐵的顏色，原因有兩點(diǎn)二、它的坯料是土坯。2、偽劣材軋制的溫度不標(biāo)準(zhǔn)，他們的鋼溫是通過(guò)目測(cè)的，這樣無(wú)法按規(guī)定的奧氏體區(qū)域進(jìn)行軋制，異型管鋼材的性能自然就無(wú)法達(dá)標(biāo)。
