DIN2391 St30Ai high-precision seamless steel yeeb nkab yog ua los ntawm cov pa roj carbon zoo, precision kos, tsis-oxidizing ci kev kho cua sov (NBK xeev). Sab hauv phab ntsa ntawm cov yeeb nkab steel yog txhuam nrog cov cuab yeej tshwj xeeb thiab ntxuav hauv siab. Cov yeeb nkab steel yog them nrog cov roj tiv thaiv xeb rau kev tiv thaiv xeb thiab ob qhov kawg yog kaw rau kev tiv thaiv plua plav.
Cov yam ntxwv tseem ceeb ntawm DIN2391 St30Ai seamless precision steel yeeb nkab yog: siab precision, zoo tiav, zoo sab hauv phab ntsa huv si, steel yeeb nkab tuaj yeem tiv taus siab, tsis deformation tom qab txias dabtsi yog khoov, tsis muaj kab nrib pleb tom qab nthuav thiab flattening, thiab tuaj yeem raug rau ntau yam kev nyuaj. deformation thiab mechanical processing.
