 Cr adds strength to the m꧙aterial and V gives more grain 🐭refinement. (Fine Grain Size of 3 to 5)

三男玩一女(nv)三A片_国产精(jing)品va无(wu)码二区:Cr可展现出档案资料(liao)的程(cheng)度(du), 而V可提供(gong)了更佳的晶💟相空间布(bu)局.

 Toughness of this Fine Grained Alloy steel is better than Coarse Grained Plain 💯Carbon steel.

三男(nan)玩(wan)一女三A片_国产(chan)精品va无码(m🍃a)二区:精密(mi)仪器(qi)的晶相(xiang)规划比粗拙(zhuo)的晶相(xiang)规划使合金(jin)类钢兼有最(zui)好的耐磨性.

Because of better grain structꦬures, this material gives better results after Heat Treat🐓ment w.r.t. uniform Hardness.

是(shi)由于效果更(geng)加好的晶(jing)相🉐布(bu)局(ju)图, 镍钢(ꦬgang)钢(gang)在热(re)防范后应该只(zhi)不过得到效果更(geng)加好的机可,比(bi), 区别的坚硬程度.

 Presence of alloy elements like V gives more stable micro🐻structurಌe.

三(san)男玩一女三(san)A片_国产精(jing)品(pin)va无(wu)码二区:硬质合金(jin)重元素,不是而是V, 的的存在(zai),使信(xin)♓息具备有快又(you)稳定的分子(zi)运动设计(ji𓂃).

 Spherodized annealed structure adds ductility to the material as required for Cold Fo🅠rming Operation.
