Stainless Steel Grade Charts

 

  • 303 stainless steel: In terms of composition, 303 stainless steel is comparable to 304 grade. For the 304 grade with sulfur added, it only denotes 303. Sawdust leakage during machining is a sign of a material’s machinability due to sulfur. Sulfur, on the other hand, makes materials less resistant to corrosion. The corrosion resistance of 303 quality material is thus lower than that of 304 quality. This kind of metal belongs to the eustenitic stainless group, does not retain sections, and has not undergone heat treatment.

The most popular grade of stainless steel is 304, which is utilized in a variety of products. Its composition of 18% chromium and 8% nickel makes it a stainless steel of high grade that may be used in a variety of settings. All types of foreign warfare goods, including cutlery, knives, culinary utensils, and everyday ornamental items, may be made from this stainless steel grade. The use of stainless steel in severely corrosive settings is not advised because, like all stainless steel, 304 grade has a strength limit. The unit’s 304 high-quality components are all male and of European descent.

  • 304L stainless steel: The two grades’ varied carbon ratios are the sole significant distinction between 304L and 304 stainless steel. The carbon percentage of 304L steel is quite little. The range of carbon hose is somewhat larger if it is standard 304 grade. A material’s resistance to corrosion may somewhat increase at certain thicknesses as the quantity of carbon in the substance decreases. Low carbon also affects the weldability characteristics, but little at the edges. Flat and hexagonal materials are often recommended to be made of 304L grade steel. The 304L materials that are offered by our firm, are mostly flat bars, hexagonal bars, and certain thick diameter bars.
  • 316 stainless steel is a premium grade of stainless steel. The most popular auto-stainless material after loading is stainless steel of grade 304. There are other nickel 316 grades available in addition to the 304 grade. Molybdenum, which is not present in 304 grade but is accessible in 316 quality, significantly boosts both elements’ corrosion resistance in addition to adding additional nickel.

The quantity of carbon in 316L stainless steel is the most significant—and maybe only—difference between it and 316 quality stainless steel. L stands for low in the English language, and 316L stainless steel has a carbon content of 0.03% or less.

316Ti stainless steel is a sought-after grade of stainless steel that is commonly referred to as 4571 or 1.4571. Due to the body’s high melting temperature, combining the body with the material is quite challenging. The body increases the material’s resistance to both corrosion and advancement. Due to this, all 316Ti, 1.4571 grade materials offered by Our Stainless are materials of European origin.

  • The stainless steel grade 310, sometimes referred to as 310 stainless or 310 S quality stainless steel, has very high levels of nickel and chromium. The temperature ranges of both elements are specifically combined in this material, allowing it to tolerate very high temperatures. Only a French company, Ugitech, produces 310 stainless steel products that can withstand temperatures of up to 1000 degrees, and the Ugitech materials produced at Our have the best corrosion and heat loss characteristics.
  • 420 Stainless Steel: Depending on how much carbon is present, many varieties of 420 stainless steel are generated. For instance, 1.4021 and 1.4028 are stainless steel grades that are versions of 420. There are three types of the 420 clean materials that are most often used and manufactured. The first of them is X20Cr13, or 1.4021. X30Cr13 pairs are 1.4028. Version three is 1.4034, often known as X46Cr13. Only the quantity of carbon varies across the three 420 classes.
  • 431 Stainless Steel: The QT800 or QT900 heat treatment process is often used to make 431 stainless steel, also known as 4057 stainless steel. In QT, quenched and tempered are used. It stands for heat-treated material in QT material, and the number next to it indicates that it has left the least amount of separation at its boundaries after heat treatment. In conclusion, the quality of 431 (1.4057) grade materials accessible in the US with QT800 heat treatment is at least 800 MPA. Our stocks of this premium stainless steel range in size from six millimeters to 250 millimeters.
  • 430 stainless steel: This material has an excellent sheen. This kind of stainless steel, which can retain a magnet, is not very rust-resistant. Due to its cost benefit, this stainless steel grade influences choices in environments where corrosion is not a concern. Its average values are higher than its mechanical characteristics.
