21、.12216.72辩别假冒伪劣钢材的几点办法伪劣钢材易出现折叠。折叠是钢材表面形成的各种折线，这种缺陷往往贯穿整个产品的纵向。产生折叠的原因是由于伪劣厂家追求高效率，压下量偏大，产生耳子，下一道轧制时就产生折叠，折叠的产品折弯后就会开裂，钢材的强度大下降。 2伪劣钢材外表经常有麻面现象。麻面是由于轧槽磨损严重引起钢材表面不规则的凹凸不平的缺陷。由于伪劣钢材厂家要追求利润，经常出现轧槽轧制最超标。 3伪劣钢材表面易产生结疤。原因有两点：(1)伪劣钢材材质不均匀，杂质多。(2)伪劣材厂家导卫设备简陋，容易粘钢，这些杂质咬人轧辊后易产生结疤。 4伪劣材表面易产生裂纹，原因是它的坯料是土坯，土坯气孔多，土坯在冷却的过程中由于受到热应力的作用，产生裂痕，经过轧制后就有裂纹。 5伪劣钢材容易刮伤，原因是伪劣材厂家设备简陋，易产生毛刺，刮伤钢材表面。深度刮伤降低钢材的强度。 6伪劣钢材无金属光泽，呈淡红色或类似生铁的颜色，原因有两点:(1)它的坯料是土坯。(2)伪劣材轧制的温度不标准，他们的钢温是通过目测的，这样无法按规定的奥氏体区域进行轧制，钢材的性能自然就无法达
