Standard stainless steel tube processing method rusty steel tube, delineated three hardness test method, the user can choose different ways depending on the material thickness and the state as well as its premise to detect its hardness. Rockwell hardness detect hardness of stainless steel embossed plate, generally designated use HRC and HRB two rulers, for annealed stainless steel, for its different varieties, usually in the range 88-100HRB, and quenched and tempered steel , it is generally in the range of hardness 32-50HRC. The biggest reason for this problem rusting stainless steel pipe, stainless steel is due to renovation, there will be a lot of decoration paint, etc., these things have erosion is likely to damage the surface of stainless steel, you just look washed with water, with a rag clean it, or find a home for you who want to make stainless steel processing rust or rust rub some cream, and then not let them come directly to the hotel to help you deal with what a stainless steel door, do not do self-advocate with soap and water or detergent, etc. to deal with. In hardness testing stainless steel and stainless steel tube is often used to, stainless steel tube test does not apply to a larger force applied to a thin sheet of hardness testing, especially in the less possible, use 1.2mm Vickers hardness detection. Chongqing stainless steel processing of stainless steel hardening heat treatment and quenching and tempering main purpose is hardening, after the hardening material is heated to a temperature below the phase transition point, the use of appropriate hardening prick rapid cooling. In order to improve the toughness after tempering is quenched material, to obtain the desired degree of heat treatment is carried out. It is heated to a temperature as shown in the following transformation point Xu is cooled. It is believed that the heating rate and holding time is basically the same annealing conditions. For ferritic stainless steel door type, the purpose is to soften the tissue heat and adjust end product organization, often annealing. Standard incubation time is based on the material thickness or diameter for every 25 mm, to be incubated for 1 hour or more terms, from the perspective of preventing deformation, should avoid excessive heating rate.
