STS309S - Siab-Chromium-Nickel Austenitic Alloy Rau Siab-Tub Kub Oxidation Resistance

Txheej txheem cej luam

STS309S yog lub siab -chromium-nickel austenitic stainless hlau, tsim los rau siab heev - kub daim ntawv thov yuav tsum tau oxidation zoo heev thiab carburization kuj. With 22.00-24.00% chromium and 12.00-15.00% nickel, it forms a dense protective oxide film that can withstand continuous service at temperatures up to 1038℃and short-term peaks up to 1100℃, even in sulfur-containing atmospheres. Nws yog qib qis- carbon qib (C Tsawg dua lossis sib npaug li 0.08) uas muaj qhov zoo weldability thiab ductility, thiab tsis yog hlau nplaum hauv lub xeev annealed. Nws cov ntsiab lus alloy siab ua rau nws tsim nyog rau cov khoom siv hluav taws xob kub uas raug oxidation hnyav thiab thermal cycling.

Core Zoo

High chromium- cov ntsiab lus npib tsib xee muab zoo heev - kub oxidation thiab carburization kuj; ruaj khov kev ua tau zoo nyob rau hauv thermal cycling; Cov ntsiab lus qis carbon txhim kho weldability thiab tiv thaiv intergranular corrosion; tsis yog-magnetic; zoo ductility thiab formability; haum rau huab cua siab - qhov kub thiab txias mus txog 1038℃kev pabcuam txuas mus ntxiv.

Daim ntawv thov

Cov khoom siv hluav taws xob muaj hluav taws xob (burners, qhov rooj, kiv cua), cua sov kho fixtures, boiler raj, petrochemical cracking khoom, thiab siab -kub kiln linings yuav tsum superior oxidation kuj.
