Khaub Taws Kub Taws Seamless Tubing JIS G3429 STH22

JIS G3429, Cov txheej txheem Japanese no qhia txog seamless steel yeeb nkab uas siv los tsim kev lag luam cov tshuab hluav taws xob ua muaj roj thooj. Cov kav dej raws li JIS G3429 yog tsim los ntawm kev sib txuas ntawm cov yeeb nkab thiab kev siv xov ntau thiab feem ntau, cov yeeb nkab tsis yog cua sov kho thaum siv thiab ua. Qhov kawg ntawm lub yeeb nkab yuav tsum tsis meej yog tias tsis muaj kev txwv. Hom STH22 yog cov ntaub ntawv siv dav hauv cov ntaub ntawv siab.

 

Nws muaj tsib hom hom rau qhov kev faib tawm raws li kab ntawv ntawm cov tshuaj chemical:

C-hlau hlau: STH11, STH12;

Cr-Mo steel: STH21, STH22;

Ni-Cr-Mo steel: STH31.

 

SHEW-E STEEL muab JIS G3429 qib STH22 hauv cov loj thiab cov lus qhia nram qab no:

Siv cov khoom siv: 34CrMo4
