ST37-2 is a commonly used structural steel grade according to the German DIN 17100 standard. However, when it comes to flanges, the material specification is typically indicated as part of the flange standard. ST37-2 is not specifically a flange material grade.

Flanges are typically manufactured from a variety of materials, including carbon steel, stainless steel, and alloy steel, depending on the specific requirements of the application. The material specification for a flange should comply with the relevant flange standard, such as ASME B16.5 for pipe flanges or EN 1092-1 for flanges in Europe.

If you are looking for flanges with specific material requirements, it would be best to consult the applicable flange standards or contact a reputable flange manufacturer or supplier for assistance in selecting the appropriate material grade for your application. Contact Omaaforged
