Dab tsi yog cov khoom siv stkm12c?
JIS G 3445 Qib STKM 12C Tubesyog cov nqi qis qis qis Carbon Steel Tubes nrog max 020% cov ntsiab lus carbon nrog kev sib xyaw ntawm max 060% manganese yooj yim rau kev tsim thiab zoo.
STKM 12B carbon steel yeeb nkab thiab STKM 12C carbon steel round yeeb nkab yog ob hom carbon steel yeeb nkab uas muaj cov ntsiab lus sib txawv ua raws li Japanese Industrial Standard (JIS) G3445. Qhov sib txawv tseem ceeb ntawm ob cov kav hlau no yog lawv cov ntsiab lus carbon, nrog STKM 12B muaj cov ntsiab lus qis dua thiab STKM 12C muaj cov ntsiab lus siab dua me ntsis. Vim qhov sib txawv ntawm cov ntsiab lus carbon, lawv cov khoom siv kho tshuab kuj sib txawv. Feem ntau, raws li cov ntsiab lus carbon nce, lub zog thiab hardness ntawm cov yeeb nkab steel yuav nce.
