欧标高锰钢与国产Mn13之间还是有不少差别的。Mn12、X120Mn12、ZGMn13、1.3401、K700、A128
Shanghai GaoGao Company is one of biggest high manganese steel supplier in China. Product line includes Mn13、X120Mn12、ZGMn13。
Steel plate products are both normal standard and special standard.
The normal standard thickness is 6mm ~ 30mm. according to your special require, 1.0mm thickness or 100.00mm thickness of steel plate can be offered.
Square steel can be rolled based on order, round steel is in stock but quantity is limited. Act for customers in order for forward contract.

专业高锰耐磨钢那么多年来,虽然现在一路上那么多的荆棘,我们一样坚持着。
X120Mn12执行欧标,Mn13执行国家企业标准。价格性能都有区别。
含锰较高时,有较明显的回火脆性现象。
锰有促进晶粒长大的作用,因此锰钢对过热较敏感t在热处理工艺上必须注意。这种缺点可用加入细化晶粒元素如钼、钒、钛等来克服;
当锰的质量分数超过1%时,会使钢的焊接性能变坏;
锰会使钢的耐锈蚀性能降低。
(1)锰可以提高钢的淬透性。
(2)锰对提高低碳和中碳珠光体钢的强度有显著的作用。
(3)锰对钢的高温瞬时强度有所提高。
