General Requirements thiab Ordering Information

Daim hlau yuav tsum paub meej rau ASTM A20 / A20M.

• Kev sim thiab rov ua cov txheej txheem, cov txheej txheem;
• Tso cai tolerances nyob rau hauv qhov ntev thiab loj, zoo;
• Kho qhov tsis xws luag;
• Kos npe, thauj khoom thiab xaj cov ntaub ntawv;
• Cov coils raug cais tawm ntawm qhov tshwj xeeb no yog tias txiav rau daim hlau daim ntawv.

Khoom siv thiab kev tsim khoom

Cov hlau yuav tsum raug tua thiab ua rau ib qho ntxhib austenitic grain loj xyaum.

Kev kho cua sov

ASTM A515 daim hlau thickness nyob rau hauv 50 hli [2 nti] thickness thiab hauv qab yog ib txwm muab nrog raws li-dov mob, tshwj tsis yog nws tau txiav txim raws li thov.
Cov phaj siab tshaj 50 hli [2 nyob rau hauv] hauv thickness yuav tsum normalized.
