Vim li cas TP316L rau High-Pressure Systems?
✔ Superior Corrosion Resistance
Cov ntsiab lus molybdenum 2-3% txhim khu kev tiv thaiv rau:
Chloride pitting
Kev txhim kho corrosion
Acid ib puag ncig
✔ Cov ntsiab lus carbon tsawg
Tsawg dua los yog sib npaug rau 0.03% carbon minimizes carbide nag lossis daus thaum vuam, txo cov kev pheej hmoo corrosion intergranular.
✔ Kev ntsuas siab zog
SCH 80 phab ntsa thickness ho nce tso cai ua hauj lwm siab piv rau SCH 40.
✔ Zoo Weldability
Tsis xav tau preheating, thiab tom qab -weld corrosion kuj tseem ruaj khov.
