SUS304不锈钢304耐蚀性钢板#耐高温钢性能SUS304
SUS304 SUS304L have all features; The corrosion resistance and good heat resistance; Or eliminate stress after welding, also can maintain good corrosion resistance; Deep impact resistance, good polishing. Applied to the high resistance to intergranular corrosion of chemical, coal, petroleum environment instruments and equipment; - outdoor decorative materials, heat resistant parts and heat treatment are difficult parts. 【 SUS304L carbon 0.03 or less 】 【 SUS304 carbon 0.08 or less 】 is SUS304 austenitic steel, basic use is the most widely: good corrosion resistance and heat resistance; Low temperature resistance and mechanical properties; Single-phase austenitic organization, no heat treatment hardening phenomenon (non-magnetic, using temperature - 196-800 ℃).
