Hardness Testing Method of Strip Steel

Strip steel introduction:

Strip steel is a narrow and long steel plate produced to meet the needs of different industrial sectors. Its width is generally within 300mm, but with the development of the economy, the width is no longer limited.

Strip steel is supplied in coils, with the advantages of high dimensional accuracy, good surface quality, easy processing, and material saving. Like steel plates, strip steel is divided into ordinary strip steel and high-quality strip steel according to the material used; it is divided into hot rolling and cold rolling according to the processing method.

Strip steel is widely used in the production of welded steel pipes, as blanks for cold-bent steel, and in the manufacture of bicycle frames, rims, clamps, washers, springs, saw blades and blades.

Strip steel products should be graded according to the hardness according to the degree of annealing. Different subsequent processing requires the use of strip steel materials with different hardness levels.

The detection of annealing hardness is of great significance in the production and use of strip steel products. The iqualitrol portable surface Rockwell hardness tester is very suitable for testing the hardness of strip steel.

Strip steel includes cold-rolled strip steel, bright strip steel, stainless steel strip, galvanized steel strip, tinned steel strip, etc. These strip steel products need to be annealed after cold rolling. Most products are graded according to the degree of annealing.

Different subsequent processing requires the use of strip steel materials with different hardness levels. The detection of annealing hardness is of great significance in the production and use of these strip steel products.

The iqualitrol portable Webster hardness tester is a more convenient hardness testing instrument. It can quickly test the hardness of moving strip steel products on the production line. The test process only takes 1 second. Although the resolution of this instrument is not high, it can meet the requirements for judging the qualified hardness and hardness level of strip steel. The use of this instrument is of great significance for strip steel processing.
