南祥螺紋元件取自優(yōu)質(zhì)材料、經(jīng)精加工、真空淬火精制而成。我公司螺紋元件采購國內(nèi)-線品牌生產(chǎn)的W6Mo5Cr4V2材料，材料經(jīng)過理化分析、金相分析檢驗合格。所有產(chǎn)品經(jīng)數(shù)控化設(shè)備加工、利用真空設(shè)備淬火，硬度控制在HRC60°-62°之間，具有很高的耐磨性和良好的韌性。同時也可采用38CrMoAL，經(jīng)調(diào)質(zhì)氮化處理，氮化深度達(dá)0.50-0.60mm,硬度控制在HV950-1100。根據(jù)客戶要求也可采用國外高耐磨的粉末合金鋼，如:MM60、WR5、WR13、 WR14、SAM10、SAM39等，對特殊要求耐腐蝕環(huán)境使用元件，還可提供316L、SX737、C276高耐腐蝕材料。

　　Nanxiang screw elements are made of high-quality materials, refined and vacuum quenched.Our company's screw elements purchase W6Mo5Cr4V2 materials produced by domestic-line brands， and the materials are qualified through physical and chemical analysis and metallographic analysis. All products are processed by CNC professional equipment and quenched with domestic first-class professional vacuum equipment. The hardness is controlled between HRC60° -62°， with high wear resistance and good toughness. At the same time, 38CrMoAL can also be used, after quenching and tempering nitriding, the nitriding depth reaches 0. 50-0.60mm, and the hardness is controlled at HV950- 1100. According to customer requirements, foreign powder alloy steels with high wear resistance can also be used, such as: MM60, WR5, WR13, WR14, CPM10V, CPM9V. And 316L,SX737, C276 high corrosion resistance materials are for special requirements for corrosion-resistant environment components.
