                           XAR400,xar400耐磨板技术支持

XAR400, XAR450, XAR500 series special wear resistant structure steel

Germany Thyssen Krupp Stahl AG (thyssenkrupp steel company, hereinafter referred to as "the TKS") since the mid - 1960 - s to start producing the high wear-resisting performance of the special structure of steel, quenching and quenching and tempering heat treatment, with dense martensite or martensite and bainite microstructure. Production of steel plate thickness up to 100 mm. In addition to the traditional XAR 400, XAR 450, XAR 500 level, the TKS also successfully developed three new level -- for low and medium wear XAR 300 normalized steel, the higher temperature of the environment using the XAR 400 w could satisfy the requirement of higher wear and XAR superhard level 600. Thus, selection of steel plate coverage of up to 300 ~ 300 hb hardness, almost on any use of the environment to provide the appropriate solution. All levels, the most commonly used is 400, XAR hardness value is 400 hb, its service life can amount to about 5 times the traditional structure of steel plate. For XAR steel treated by quenching and quenching and tempering, due to the high hardness of the steel instead of carbon content is proportional to the, in order to obtain the required high hardness, keep certain carbon content in steel is necessary. Steel of nominal hardness hb 400, for example, must keep about 0.14% of the carbon, at the same time, by adding B, Mo, Ni, balanced performance to ensure that the steel plate inside and outside. Also note that all XAR steel also contains less than 1.5% Cr. All kinds of wear test has shown that the wear resistance of hoisting steel, wear resistance slightly acidic medium, in particular, is very effective. Normalizing special wear-resisting steel rolling XAR300 has good surface quality, especially applicable to the need for thermoforming purposes.

XAR400, XAR450, XAR500 series wear resistant steel is a high-tech materials, it will be uniform high hardness, good toughness, low alloy content and excellent machining performance perfectly set at a suit, make it become the ideal material for many applications.

XAR400耐磨板热成型
XAR 300可在850-1000℃进行热成型,成型及空冷后钢板的良好性能不会失去。

XAR400机械加工
XAR 300/400(W)/450/500不仅耐磨性能优异,如果采用重型加工机床及坚硬的硬质合金刀具,其机械加工性能也同样出色。但切削及进刀速度应根据材料的硬度相应调整。

XAR400热处理
 
XAR400耐磨板的性能是通过奥氏体化后,在特殊装置中进行淬火,必要时再加回火获得的。对XAR 400(W)/450/500也可在热轧后直接进行淬火。具体的热处理工艺与化学成分和钢板厚度有关。为使硬度不下降,热处理后,要避免再次加热XAR 400/450/500到250° C以上,XAR600 300° C以上,XAR 400W 400° C以上。 XAR 300采用880-960℃正火或正火轧制,对较薄钢板和在一些特殊情况下,可能需要延时冷却或回火。
 
XAR400钢板热切割021-37002018
 
采用火焰切割方法。对于较簿的钢板,为减少变形可采用等离子或激光切割。
30mm(XAR 400), 20mm (XAR 300/450) 或10mm(XAR 400W/500)厚度以下钢板的火焰切割通常不需要预热。但是,如果工件温度低于5° C,或者在后续工艺中要对切割边进行冷成型,为了防止出现冷裂,应考虑预热到150° C左右。厚度超过10mm的XAR 600一般都需要
150° C左右预热。

XAR400耐磨钢板焊接:
 
参照一般的焊接要求,可对本钢板进行手工和自动焊接。为防止焊缝出现冷裂,只应采用低氢焊材。采用奥氏体填料焊,通常不需要预热。采用铁素体填料焊,XAR400/450可能需要预热;而XAR500则应按照SEW 088标准,根据板厚相应预热。焊接的预热温度取决于钢板的厚度以及焊接结构的残余应力状态。工作温度不应超过250° C。可通过堆焊或金属喷涂耐磨层来进一步提高工件的耐磨性能(我们将提供详细的焊接资料供你参考)。
