At Bergsen Metals, we offer a full inventory of stainless steel products in the following grades and sizes:
15-5 Stainless Steel
15-5 is another martensitic stainless steel that is precipitation-hardening. It is superior at resisting corrosion and can be utilized for applications that necessitate transverse properties.
303 Stainless Steel
303 is also in the austenitic family. It is high in machinability because it has more sulfur and phosphorus than 304. It is used to create fittings for aircraft, gears, bolts, and nuts.
304 / 304L Stainless Steel
304 is the most common grade of austenitic stainless steel, while 304L is a variation with less carbon. 304 is used in many applications, including automotive, food handling, nuclear components, and shipping drums. 304L is beneficial for welding.
316 / 316L Stainless Steel
316 is the next most common austenitic stainless steel, and 316L is the low-carbon variation. These have better resistance to specific types of corrosion. 316 is often used to build nuclear plants, while 316L is beneficial for the chemical and pharmaceutical industries.
321 Stainless Steel
321/321H are also austenitic stainless steels that contain more titanium. 321H is higher in carbon, enabling better use in higher temperatures. Both 321 and 321H are used for chemical processes and refineries.
347 Stainless Steel
347 and 347H are similar to 321/321H, but they have more niobium and tantalum, which desensitizes it in welding. It is often used to create parts for airplanes and cars, as well as for tanks that store chemicals.
17-4PH (630) Stainless Steel
630, also called 17-4 Precipitation Hardening, is a type of martensitic stainless steel with chromium and copper. It is very strong and resistant to corrosion. It can be used for offshore applications and nuclear waste, as well as airplane and mechanical parts.
17-4 (630 H1150) Stainless Steel
630 H1150 is similar to 630 HH1150, but it has only been heat treated once. It is softer than the regular 630 alloy and can be used in the same types of applications.
440C Stainless Steel
44oC is very high in carbon, and it is the hardest of all stainless steels. It can be used to create knives, surgical implements, nozzles, bearings, and valves.
