西安不锈钢板的折弯特性
1、因导热性比普通低碳钢差，延伸率低，导致所需变形力大;
2、不锈钢板料在折弯时与碳钢相比有强烈的回弹倾向;
3、不锈钢板相对于碳钢由于延伸率低， 折弯时工件折弯角R要大于碳钢，否则有出现裂纹的可能;
4、由于不锈钢板硬度高，冷作硬化效应显著因此在选择压弯刀具时要选择热处理硬度应达到60HRC以上的工具钢， 其表面粗糙度要比碳钢的压弯刀具高一个数量级。
西安不锈钢板的折弯特性，一般来说：
1、单位尺寸下，板材越厚，所需折弯力越大，而且随着板厚增大在选择折弯设备时折弯力的裕量应该更大;
2、单位尺寸下，抗拉强度越大，延伸率越小，所需折弯力越大，折弯角应该越大;
3、设计图中板厚与折弯半径对应情况下，根据经验，一道弯工件的展开尺寸为直角边相加减去两个板厚，完全可以满足设计精度要求，根据经验公式计 算展开量可简化计算过程大大提高生产效率;
4、材质的屈服强度越大，弹性 回复量就越大，为获得折弯件90度的角度，所需压刀的角度就要设计的越小。相对于碳钢相同板厚的不锈钢折弯角较大，这一点应特别注意否则会出现压弯裂纹，影响工件强度。
公司至成立以来，以“诚信、合作、双赢、发展”为经营宗旨，坚持“价格**、用户、信誉”的营销理念，在市场上获得了良好的口碑。
