ZGMN13 Non-Magnetic Steel Plate
ZGMn13, equivalent to DIN 1.3401 standard steel X120Mn12, is a non–magnetic abrasion resistant steel well known as Hadfield steel. It’s known for its’ high impact strength and abrasion resistance. In the work-hardened state, it achieves up to 600 HB hardness.
ZGMn13, which is the German standard X120Mn12. This type of steel contains 10% to 15% manganese, and the carbon content is relatively high, generally 0.90% to 1.50%, most of which are above 1.0%. The pre-processed Mn13 rolled steel plate has a much higher wear resistance than the imported low-alloy wear-resistant steel under no impact or low pressure environment, and of course it is much stronger than the domestic wear-resistant steel NM420. And the cutting and welding performance is also very good.

ZGMn13 characteristics and scope of application:
It has high tensile strength, plasticity and toughness, and non-magnetic, even if the parts are worn to a very thin level;
It can still withstand large impact loads without breaking, and can be used to cast various impact-resistant wear parts;
Such as ball mill liner, excavator tooth, crusher tooth plate, etc. Generally used for simple structure;
Low-impact castings that are mainly wear-resistant are required, such as liners, tooth plates, broken walls, rolling mortar walls, roller sleeves and shovel teeth.
