鉻(Cr)：在結(jié)構(gòu)鋼和工具鋼中，鉻能提**度、硬度和耐磨性，但同時(shí)降低塑性和韌性。鉻又能提高鋼的抗氧化性和耐腐蝕性，因而是不銹鋼、耐熱鋼的重要合金元素。 </p> <p> 、鎳(Ni)：鎳能提高鋼的強(qiáng)度，而又保持良好的塑性和韌性。鎳對(duì)酸堿有較高的耐腐蝕能力，在高溫下有防銹和耐熱能力。但由于鎳是較稀缺的資源，故應(yīng)盡量采用其他合金元素代用鎳鉻鋼。 </p> <p> 、鉬(Mo)：鉬能使鋼的晶粒細(xì)化，提高淬透性和熱強(qiáng)性能，在高溫時(shí)保持足夠的強(qiáng)度和抗蠕變能力(長(zhǎng)期在高溫下受到應(yīng)力，發(fā)生變形，稱蠕變)。結(jié)構(gòu)鋼中加入鉬，能提高機(jī)械性能。還可以合金鋼由于火而引起的脆性。在工具鋼中可提高紅性。 </p> <p> <br /> </p><p>

如果處理件的局部在熱處理前有殘存的氧化皮,加熱后有氧化皮殘存的部位和沒有氧化皮的部位,會(huì)出現(xiàn)氧化皮的厚度和成分上的差異,引起酸洗后表面不均勻,所以不僅要注意超終的熱處理,而且也要充分注意中間熱處理和酸洗。 </p> <p> 表面光潔度不同時(shí)的影響,如果表面光潔度不同,即使同樣加熱,其表面粗糙處和精細(xì)處的氧化皮也不相同。例如,在局部缺陷經(jīng)過(guò)清理的地方和沒清理的地方,形成氧化皮的狀況不同,故引起酸洗后工件表面不均勻。 </p> <p> 爐內(nèi)氣氛的差異爐內(nèi)氣氛在各局部的不同,氧化皮的形成一也會(huì)有變化,這也是造成酸洗后不均勻的原因。所以,在加熱時(shí),爐內(nèi)各部位的氣氛必須相同。所以也必須考慮氣氛的循環(huán)。呼和浩特不銹鋼六角棒咨詢電話-江蘇進(jìn)百洪。</p><div style="width:100%;text-align: center;"><img
