    • Herein are disclosed steel forms having stainless steel exteriors that pass a OT-bend Advanced T-bend Test. One steel form has a stainless steel exterior; the steel form includes a core region that comprises at least 55 wt.% iron which is metallurgical^ bonded to a stainless steel coating that consists of a stainless steel region and a bonding region. The stainless steel region can have a thickness of about 1 μΐη to about 250 μΐη, and a stainless steel composition that is approximately consistent across the thickness of the stainless steel region. The stainless steel composition can include an admixture of iron and about 10 wt.% to about 30 wt.% chromium. The bonding region is positioned between the stainless steel region and the core region, has a thickness that is greater than 1 μΐη and less than the thickness of the stainless steel region, and has a bonding composition. The bonding composition can include an admixture of iron and chromium, with a chromium concentration proximal to the stainless steel region that is approximately equal to the chromium concentration of the stainless steel region and has a chromium concentration proximal to the core region that has less than about 5 wt.% chromium.
    • 本文公开了具有通过OT弯曲高级T形弯曲试验的不锈钢外部的钢制形式。 一种钢结构外形为不锈钢; 钢的形式包括核心区域,其包含至少55重量%的铁,其被冶金地结合到由不锈钢区域和结合区域组成的不锈钢涂层上。 不锈钢区域的厚度可以约为1微米& 至约250μ&标识;以及不锈钢组合物,其在不锈钢区域的厚度上大致一致。 不锈钢组合物可以包括铁和约10重量%至约30重量%铬的混合物。 接合区域位于不锈钢区域和芯部区域之间,其厚度大于1μ&idiagr;&eegr; 并且小于不锈钢区域的厚度,并且具有接合组成。 粘合组合物可以包括铁和铬的混合物,铬浓度接近不锈钢区域,其大致等于不锈钢区域的铬浓度,并且具有接近核心区域的铬浓度,其具有小于约 5重量%铬。
