304L stainless steel is a kind of universal stainless steel material.
304L stainless steel grade:
The old standard JB/T 4237-1992 corresponds to 00Cr19Ni10
New standard GB/T 20878-2007 Stainless steel and heat resistant steel grades and chemical composition
And GB 24511 2009 stainless steel coils and strips for pressure bearing equipment
The above corresponds to 022Cr19Ni10, which contains about 0.03% carbon
Uniform digital code S30403 is different from S30408 of 304

This is the most cost effective grade of steel. So the 304L Stainless Steel coil Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content.  The low carbon version, 304L coils are very good for welding applications as they have less carbide precipitation and less localized corrosion.

304L Characteristic machining technology


1D -- The surface has discontinuous granular shape, also known as fog surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B -- Silver white with better gloss and flatness than a 2D surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
Ba - Excellent surface gloss, high reflectivity, like a mirror surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
No.3 -- Good gloss, coarse grain surface.
Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).
No.4 -- Good gloss, fine lines on the surface.
Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
HL -- Silver grey with hair streaks.
Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.
MIRRO -- Specular.
Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
