Stainless Steel

As a trusted 316 & 304 supplier, we supply fully certified and 100% traceable material that is ROHS compliant. Consequently, we ensure the highest quality. However, if you are not sure what you’re looking for? Feel free to contact us now.

Stainless Steel Grades:

304/304L

304 references the type of composition that the stainless is made of. First of all, when you have stainless steel, you are mixing it with different metals and form it. Secondly, 304 happens to be the most commonly used type of stainless. In conclusion,  it is also known as 18-8 because it is 18 percent chromium and 8 percent nickel. Whereas, the ‘L’ stands for ‘low carbon’.

316/316L

It is important to note that this is the second most commonly sold stainless that interacts with salt water or corrosive chemicals. Whereas, the main reason it is used over the 304 is that this is an 18-12* metal. Consequently, this additional metal and this higher focus on Nickel. Therefore, it is much more resilient to the forces of water over 304 steelworks. Moreover, you’ll most often see these in ship crafts, dams, barges, and docks.

*= The average nickel amount in 316 bars ranges from 10-14 with 12 being the most common percentage.

The Guidelines for ASTM

What is ASTM?

ASTM is an international foundation for setting standards. Whereas we have been in business for several decades. Above all, most of everything American made will adhere to the guidelines.

ASTM A276/A276M

This is the standard for the specification of stainless bars and shapes presented by ASTM. Whereas, the standard pertains to hot and cold rolled steel (referred to as hot-finished and cold-finished). Additionally, it includes what grades to keep them to. Furthermore, this guide means that we adhere to all of the proper standards for creating and forging bars and shapes (anything above 3” in any of the three fundamental dimensions.)

ASTM A484/A484M

The Standard Specification for general requirements for stainless steel bars, billets, and forgings. The standard covers the following stipulations that alter the end product of a stainless steel product: Hot rolled, cold-rolled, annealed, and heat-treated. We follow all of the appropriate standards that pertain to the classifications described in the issued by ASTM.

ASTM A479/A479M

The standard specification for stainless steel bars and shapes for use in boilers and other pressure vessels. Whereas, this article defines the appropriate hot-rolled and cold-rolled steel. Also, how they can handle the pressure of austenitic, austenitic-ferritic, ferritic, and martensitic grades? Furthermore, we are certified and perform all of our steel manufacturing up to that grade and level.

A Note on DFARS and RoHS:

DFAR and Domestic materials are available on request. While we choose the best mills on the market regardless of region, we prefer to choose a material that is American-made. Furthermore, we do stock NonDFAR in some sizes and grades with lower costs. Therefore, if you are interested in purchasing DFAR or Domestic materials. Also, remind your sales rep to ensure that you receive DFAR or Domestic certified material. However, *not All metal used in government or defense contracts requires DFARS standards.

DFARS QUALIFYING COUNTRIES

Australia, Austria, Belgium, Canada, Denmark, Egypt, Finland, France, Germany, Greece, Israel, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, and the United Kingdom. (Per DFARS 225.872-1): Qualifying Countries. Metals Requiring Compliance. However, not All metal used in government or defense contracts requires DFARS standards. DFARS “Specialty Metals” requiring compliance (Per DFARS 252.225-7008): DFARS

What is ROHS?

It’s important to note that ROHS is to restrict certain dangerous substances commonly used in electronic and also electronic equipment. Therefore, any time you see Rohs it is being checked for the presence of Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent chromium (Hex-Cr), Polybrominated biphenyls (PBB), and Polybrominated diphenyl ethers (PBDE).

Whereas, for Cadmium and Hexavalent Chromium, there must be less than 0.01% of the substance by weight at the raw homogeneous materials level. Finally, for Lead, PBB, and PBDE, there must be no more than 0.1% of the material, when calculated by weight at homogeneous raw materials. Furthermore, any RoHS-compliant component must have 100 ppm, or less of mercury and the mercury must not have been intentionally added to the component. To conclude, in the EU, some military and medical equipment are exempt from RoHS compliance. (According to rohscompliantdefinition.com,2014)
