304/304L stainless steel plate
As the base grades of the austenite series, 304/304L stainless steels feature excellent corrosion resistance, heat resistance, low‑temperature strength and mechanical properties. They do not harden after heat treatment and are virtually non‑magnetic.
Features and Practical Uses:
difference | 304 | 304L |
Features | --Basic austenitic steel grade with the most extensive applications; --Excellent corrosion resistance and heat resistance;--Good low‑temperature strength and mechanical properties;--Single‑phase austenitic structure with no heat‑treatment hardening phenomenon | Excellent corrosion resistance compared with 304 |
| Purpose | --Class 1 and 2 tableware, exterior packaging materials, building materials, automotive parts, --medical devices, chemicals, food technology, textile industry,--ship components | -- Equipment for the chemical, coal and petroleum industries with high requirements for intergranular corrosion resistance, -- Building materials, heat‑resistant components and parts difficult to heat‑treat |
