hardened and tempered steel

基本解釋

Therefore, choosing correct hardened and tempered technology are an effective way to improve strength-toughness of low alloy high strength chain cable steel.
因此，選擇合適的調(diào)質(zhì)工藝是提高低合金高強(qiáng)度錨鏈鋼強(qiáng)韌性的一條有效途徑。
Design principle, scheme and application of controlled cooling system of non-hardened-tempered steel crankshaft produced by5000t hot die forging press have been introduced.
介紹了非調(diào)質(zhì)鋼曲軸鍛件正火冷卻系統(tǒng)的設(shè)計(jì)原理及其應(yīng)用。
The effect of hardening and tempering process on the organization and performance of high-strength and high-toughness non-hardened-and tempered steel of low carbon martensite is researched.
研究了淬火、回火工藝對(duì)低碳馬氏體型高強(qiáng)度高韌性非調(diào)質(zhì)鋼的組織和性能的影響。

調(diào)質(zhì)鋼
30CrMnSiA steel is a representative medium carbon hardened and tempered steel and becoming widely used in aviation and national defense industries. Porosity is apt to occur when welding 30CrMnSiA steel,brings on bad influence to the mechanical property of the welding joint,even affects the reliability of the product.
30CrMnSiA鋼是一種典型的Cr-Mn-Si系中碳調(diào)質(zhì)鋼,是航空工業(yè)和國(guó)防工業(yè)中的重要材料,在激光焊接過(guò)程中容易形成氣孔,對(duì)30CrMnSiA鋼產(chǎn)品焊接接頭的力學(xué)性能帶來(lái)不利影響,進(jìn)而影響產(chǎn)品的可靠性。
