At Bergsen Metals, we offer a full inventory of stainless steel products in the following grades and sizes:
Nitronic Stainless Steel
Nitronic stainless steel is an austenitic type that is incredibly strong and resistant to corrosion in comparison to other grades. When it is cold worked, it does not gain magnetic properties. It has uses in the marine industry, food processing, and the recycling of nuclear fuel. We carry nitronic 60, nitronic 50, nitronic 40 and nitronic 30 grades.

13-8 Stainless Steel
13-8 is a precipitation-hardening martensitic stainless steel. It is high in strength, resists corrosion, and is low in carbon. This is used for different components in airplanes and in the nuclear industry.
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.
302 Stainless Steel
302 is another austenitic stainless steel that is stronger than the 304 grade because it has additional carbon. It is often used to create wires, springs, washers, cables, and screens.
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 / 321H 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 / 347H 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.
630 (17-4PH) 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.
630 HH1150 Stainless Steel
630 HH1150 is a martensitic stainless steel that is the same as the regular 630 grade but has received two additional heat treatments for a softer material. It has many uses, including the food and paper industries, aircraft construction, and offshore applications.
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.
410 Stainless Steel
410 is a martensitic stainless steel that is very resistant to wear but less resistant to corrosion. It can be used for medical instruments, automotive parts, nozzles, valves, and pipelines.
410 HT Stainless Steel
410 HT is heat treated rather than annealed. It has similar characteristics and industrial uses to 410.
416 Stainless Steel
416 is a martensitic stainless steel with added sulfur for greater machinability. It is used to create components for valves, pumps, and automatic screw machines.
430 Stainless Steel
430 is a ferritic stainless steel that is generally for decorative use, such as the trim on a car. It is high in formability and moderately resistant to corrosion and high temperatures.
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.
420 MOD Stainless Steel
420 MOD is a type of martensitic stainless steel that has been both tempered and hardened. It is often used to make cutlery because it is highly polishable.
2205 / 2207 Stainless Steel
2205/2207 are widely used grades of duplex stainless steel, which is both ferritic and austenitic. It is very strong and resistant to corrosion, and it can be used in marine, chemical, oil, and gas industries.
Accuracy Bar Stainless Steel
Also known as precision ground. Accuracy bar steel comes in 303, 304, and 316 grades with the tolerance (+/-.0005)
Bearing Quality Stainless Steel
Bearing quality stainless steel is used for deep groove ball bearings. This supports both radial and axial loads. Tolerance for bearing quality stainless steel is always on the minus side.
