ASTM A335 Alloy Seamless Steel Yeeb Nkab
Lus piav qhia luv luv:
ASTM A335 feem ntau hu ua chrome moly yeeb nkab vim cov tshuaj muaj Molybdenum (Mo) thiab Chromium (Cr).Molybdenum nce lub zog ntawm cov hlau thiab Chromium (los yog chrome) yog qhov tseem ceeb ntawm stainless hlau.Qhov sib xyaw ua ke ntawm chrome moly alloy steel yeeb nkab ua rau nws zoo tagnrho rau siv hauv cov chaw tsim hluav taws xob, cov chaw tsim khoom, cov chaw siv roj av, thiab cov kev pabcuam roj av uas cov kua dej thiab cov pa thauj mus los ntawm qhov kub thiab txias heev.
Peb npaj siab los qhia peb cov kev paub ntawm kev tshaj tawm thoob ntiaj teb thiab pom zoo rau koj cov khoom tsim nyog ntawm cov nqi muag muag ntau heev.Yog li Profi Cov Cuab Yeej nthuav qhia koj tus nqi zoo tshaj plaws ntawm cov nyiaj thiab peb npaj los tsim ua ke nrog ASTM A335Alloy Seamless Steel Yeeb Nkab, Zoo yog lub Hoobkas lub neej, Tsom ntsoov rau cov neeg siv khoom xav tau yog lub hauv paus ntawm lub tuam txhab kev muaj sia nyob thiab kev loj hlob, Peb ua raws li kev ncaj ncees thiab kev ntseeg siab ua haujlwm tus cwj pwm, tos ntsoov rau koj tuaj!
