304 and 304L-----These two alloys are remarkably similar—but there is one key difference. In grade 304 stainless, the maximum carbon content is set at 0.08%, whereas grade 304L stainless steel has a maximum carbon content of 0.03%. The “L” in 304L can be interpreted as meaning extra-low carbon.

This difference of 0.05% carbon content produces a slight, but marked, difference in the performances of the two alloys.

The Mechanical Difference

Grade 304L has a slight, but noticeable, reduction in key mechanical performance characteristics compared to the “standard” grade 304 stainless steel alloy.

For example, the ultimate tensile strength (UTS) of 304L is roughly 85 ksi (~586 MPa), less than the UTS of standard grade 304 stainless, which is 90 ksi (~620 MPa). The difference in yield strength is slightly greater, with 304 SS having a 0.2% yield strength of 42 ksi (~289 MPa) and 304L having a 0.2% yield strength of 35 ksi (~241 MPa).

This means that if you had two steel wire baskets and both baskets had the exact same design, wire thickness, and construction, the basket made from 304L would be structurally weaker than the standard 304 basket.


Surface Finish stainless steel coil

No.1The surface is finished by heat treatment and pickling or processes corresponding thereto after  hot rolling
2BThe finish after cold rolling, by heat treatment, pickling or other equivalent treatment and lastly by cold rolling to give an appropriate luster
BACold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, the factory is ShuoYang or Aoxing we currenty used.
NO.4Polished with abrasive belt of grit#150~#180,have better brightness with discontinuous coarse stria, sheet or coil can be both arranged.
HLPolished with abrasive belt of grit#150~#320 on the NO.4 finish and has continuous streaks
8KThe product have excellent brightness and prefect reflexivity can be the mirror.. mirror sheet can arranged, and also mirror finish coil is also accept ordering, but need longer time to produce.

Production process about stainless steel coil--from hongwang

Raw materials are sending to hot rolling units for rolling into different sizes
Hot rolled material is annealing in cold; rolled annealing furnace and pickling in acid.
All mill rolls are grinded on precision grinding machine with proper chamfering after first shiftoperation.
All sheets are pickled in different tanks and dried on brush roll machine before dispatched.
These sheets are again annealing and are sent to straighten machine for straightening.
Inspections are done at various stages. Keep proper control overall internal process via rolling,annealin and pickling by our experienced staff.
