2004. Thanks, Bill. The need for some kind of abbreviation for stainless steel will vary by context, but if someone writes a letter to us and they want help with passivating type 304 stainless steel plates, the subject line of the letter can't be "Need 304 plates passivated", although "Need 304SST plates passivated" would suffice; "Need type 304 plates passivated" might do, but not as well.
Commonly Overlooked Equipment NSF stainless steel or standard 51 work surfaces need to be installed where food is prepared, assembled, or re-packaged. A minimum of 4 linear feet is required. However, workspace should be based on facility menu and operation. Stainless steel work table under shelving should also be stainless steel.
AISI 304 (1.4301) is a widely-used austenitic chromium-nickel stainless steel. It has excellent drawing properties and very good formability, while it is also highly corrosion-resistant. Typical uses of 304 stainless steel include sinks, kitchen equipment such as pans, tubing and much more. Type 304 is sometimes also referred to as 18/8, a ...

304 stainless steel sheet #4 finish is the brushed finish commonly seen on kitchen appliances and backsplashes. The 304 stainless steel sheet #4 finish has a PVC film on one side to help protect against scratching during fabrication and installation. Our 304 stainless steel sheet #4 finish meets the criteria for both the #3 and #4 finish.
Adding nickel to stainless steel in sufficient amounts, changes the microstructure to "austenite". 70% of commercially produced stainless steels are austenitic. The most common grade of austenitic stainless steel is 304 (1.4301). Globally, 304 accounts for more than 50% of stainless steel consumed. A common name for 304 stainless is 18/8.
Stainless steel is polished by mills in a range of forms, e.g. sheet, plate, bar & tube, but all finishes may not be available on all forms. It is important, therefore, to check that the finish is available in the form required. 1D / 1E – Hot Rolled Plate. Hot rolled, softened (annealed) with the surface de-scaled.
Yor-Lok Fittings for Stainless Steel Tubing. Use these fittings at pressures up to 9, 700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let- Lok, and Parker A-Lok fittings.
mechanical properties for specific temperature ranges; product cost; Since stainless steel resists corrosion, maintains its strength at high temperatures, and is easily maintained, it is widely used in items such as automotive and food processing products, as well as medical and health equipment. The most common US grades of stainless steel are:
AISI 304 Stainless Steel (UNS S30400) AISI 304 stainless steel (UNS S30400) is the most commonly used material in stainless steels, and is usually purchased in an annealed or cold worked state. Because SS304 contains 18% chromium (Cr) and 8% nickel (Ni), it's also known as 18/8 stainless steel.Type 304 has good processability, weldability, corrosion resistance, heat resistance, low ...

The Types 302, 304, 304L and 305 austenitic stainless steels provide useful resistance to corrosion on a wide range of moderately oxidizing to moderately reducing environments. The alloys are used widely in equipment and utensils for processing and handling of food, beverages and dairy products. Heat exchangers, piping, tanks and other process ...
Precipitation hardening grade is a combination of two stainless steel structures i.e. austenite and martensite. Both the grades i.e. 17-4 ph vs 316 offer high corrosion resistance. The metallic samples of both 17-4 PH Vs 316 are being tested in the chemical lab and mechanical labs on different testing equipment.
Working at lower temperatures will result in higher mechanical properties and smaller grain size. Cold Working. Alloy 400 is readily cold worked by virtually all cold fabrication methods. Cold working should be performed on annealed material. The alloy has a somewhat higher work hardening rate than carbon steel, but not as high as 304 stainless ...
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.
Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics.

Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys. Three general classifications are used to identify stainless steels. They are: 1. Metallurgical Structure. 2. The AISI numbering system: namely 200, …
Roughness measurements of stainless steel surfaces Introduction Ra value Surface roughness is a measure of the texture of a surface. It is quantified by the vertical deviations of a real surface from its ideal form. If these deviations are great, the surface is rough, if they are small, the surface is smooth. Roughness is typically considered to
Deep Drawing For A Wide Range of Parts. Deep draw stamping is a metal forming process to produce a seamless multi-dimensional part. Annealing is the treatment process that uses heat to alter metal's physical and chemical properties to relieve the stress of the material caused by the deep draw forming process, making the metal softer and easier to manipulate the shape of the material.
largest stainless steel family in terms of alloys and usage. They include these grades: • Iron-chromium-nickel grades corresponding to both standard AISI 300-series alloys and modified versions of these alloys. Such al-loys, which are based on type 304 (18-8) stainless steel, as shown in Fig. 1, generally contain 16 to 26% Cr, 10 to 22% Ni, and
Stainless steel is biologically inert, making it a logical choice for medical equipment such as surgical tools, trauma screws and plates. This property also makes it an ideal metal for cutlery products and kitchen appliances. Resistance to acids, bases and organic materials. Stainless steel is resistant to a wide range of compounds.
Ferritic stainless steel alloys can generally be classified into five groups, three families of standard grades (Groups 1 to 3) and two families of specialty grade steels (Groups 4 and 5). While standard ferritic steels are, by far, the largest consumer group in terms of tonnage, demand for specialty grade stainless steels is increasing steadily.
The most popular 304 grade stainless contains 18% chromium and 8% nickel — though other alloys exist within the same grade. Stainless steels of the 316 grade include less chromium — often around 16% — but increase nickel levels and add molybdenum to the mix. In most common alloys, you'll find 10% nickel and 2 to 3% molybdenum.
