347H stainless hlau coiled tubing

Stainless hlau yog cov hlau alloy siab uas muaj kev tiv thaiv corrosion ntau dua li lwm cov hlau vim muaj cov chromium ntau ntau ntawm 4 txog 30%.Stainless hlau tau muab faib ua martensitic, ferritic thiab austenitic raws li lawv cov qauv crystalline.Hauv addititon, lawv tsim lwm pab pawg hu ua nag lossis daus-hardened steels, uas yog kev sib xyaw ntawm martensitic thiab austenitic steels.
