Hot Forming
Cold Forming
Welding

304/304L/304H Stainless Steel Grade:

For maximum corrosion resistance, the material should be annealed at 1900°F (1038°C) minimum and water quenched or rapidly cooled by other means after hot working.

304/304L/304H Stainless Steel Grade:

It is quite ductile and forms easily. Cold working operations will increase the strength and hardness of the alloy and might leave it slightly magnetic.

304/304L/304H Stainless Steel Grade::

It can be readily welded by most standard processes.

Mirror

NO.1 surface treated by heat treatment and pickling after hot rolling. The appearance is silver white, matt and bright. This surface is suitable for industries that require heat resistance and corrosion resistance, and the surface brightness is not important. Common applications include industrial tank and chemical industrial plants etc..

2D surface treated by heat treatment and pickling after cold rolling. The appearance is silver white, smoother but of matt grain. Common applications include petrochemical production equipment, automotive components, building materials and water pipes etc..

After 2D treatment, the final process is lightly cold rolled by a polishing roller to obtain proper gloss. The appearance is smooth and bright, and easy to re-grind to make the surface more brighter. Common applications include building materials, tableware etc..

NO.4 is a product ground with a grinding belt of size 150-180. It has better gloss, discontinuous rough lines and finer stripes than No.3 stainless steel castings commonly used polished and sanded surfaces. Common applications include food processing equipment, home electrical products, medical equipment etc..

BA surface is also produced by cold rolling and de-scaling. It has excellent surface gloss, high reflectivity. In addition, The very smooth surface also makes this surface highly suitable for further finishing processes such as mirror polishing and chrome plating. Common applications include catering equipment etc..

HL use a polishing abrasive belt with an appropriate particle size (150-320 mesh) to grind, with obvious straight stripes. The surface is beautiful, good texture and scratch is not obvious, durable, wear-resistant. Common applications include building decoratio, elevators, vehicle parts, etc..

Mirror is produced by polishing with successively finer abrasives and buffing extensively until all grit lines from preliminary grinding operations are removed. The feature is highest reflectivity. Mainly used for interior and exterior decoration materials of automobiles and buildings.

FREQUENTLY ASKED QUESTIONS

What Is The Difference Between 304, 304L And 304H?
Why Is 304L Easier To Weld Than 304?
What Is The Yield Strength Of This Grade Stainless Steel?

What Is The Difference Between 304, 304L And 304H?

Answer:

304 is considered the most versatile and widely used austenitic stainless steel, 304L is the ultra low carbon variant of 304 stainless, while 304H is the high carbon version of the 304 stainless. Carbon content is the only chemical difference between these three grades, leading 304L to perform better in corrosive environments and be easier to weld.

Why Is 304L Easier To Weld Than 304?

Answer:

The lower carbon content in 304L helps to remove the chromium carbide precipitation that occurs during the welding, putting 304L at lower risk for intergranular corrosion even in highly corrosive environments.

What Is The Yield Strength Of This Grade Stainless Steel?

Answer:

The yield strength for 304 stainless is 205 MPa (30 ksi).

2205 Duplex Stainless Steel

2205 duplex stainless steel (2205 DSS) is a two-phase, ferritic-austenitic 22% chromium, 5 to 6% nickel, 3% molybdenum alloyed stainless steel. It contains about 40~50% ferrite in the annealed condition. 2205 has been a practical solution to chloride stress corrosion cracking problems experienced with 304/304L or 316/316L stainless. The high chromium, molybdenum and nitrogen contents provide corrosion resistance superior to 316/316L and 317L stainless in most environments. The design strength of 2205 is significantly higher than 316/316L, often permitting lighter wall construction.
