Applications

High-carbon spring and spring steels are used in many industries, unless the product is exposed to high or low temperatures, continuous shock loads or dynamic loads. Evek GmbH offers to buy spring steel and spring steel at an affordable price in a wide range. We provide delivery of products anywhere in the continent. The price is optimal.

Supply

Supply of high carbon steels for the manufacture of flat springs
are made in the form of strips, their carbon content reaches 0.85%. The steels are highly susceptible to hydrogen embrittlement, so the final steps in their production are the application of special coatings. The hardness of flat springs is within the range of 45...47 HRC.

Heat treatment

ASTM A864 provides the following heat treatment options for strip manufactured from spring-grade steels:

alloy. Hardness, HRB Carbon,% Manganese, % Silicon, %
1050 Not less than 84 0,48...0,55 0,60...0,90 0,15...0,30
1074/1075 not less 86 0,70...0,80 0,50...0,70 0,15...0,30
1095 not less 86 0,90...1,03 0,30...0,50 0,15...0,30
