304
304(L)
This is the widely used steel. It has the good corrosion resistance,thermal resistance and mechanical properties and is used for home appliances,construction materials and kitchenware,etc.
Features and Applications：
| comparison | 304 | 304L |
Features | -- Most widely used； --Better corrosion resistance and heat resistance； -- Stronger low temperature strength and mechanical properties -- One-phasic austenite structure,no hardening phenomenon after heat treatment | --superior inter-granular corrosion resistance |
Applications | -- Kitchenware 1&2,exterior materiel ,constructional material ,automobile components -- medical apparatus and instruments ,chemical technology food technology ,fiber industry, -- ship's components | constructional material ,automobile components-- medical apparatus and instruments ,chemical technology food technology ,fiber industry,-- ship's components -- equipments in chemical,coal and the petrochemical industry that request to high corrosion Resistance -- architectural materiel,heat-resistant assembly and assemblies that hart to heat treatment |
