This will produce a maximum brinell hardness of 230-300. Stress relieving Stress relieving to remove machining stresses should be carried out by heating to 650oc, holding for one hour at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. Hardening Heat up to 450-600oc, then preheat to 850oc, and to 1050oc. Harden from a temperature of 1160-1210oc followed by oil, air quenching or warm bath 550oc. Hardness after quenching is 66-68 hrc. Transformation temperatures: ac1=780oc , ac3=855oc.

Classification of steel fiber The advent of steel fiber is not long, but more and more widely used in the field, with this corresponding, steel fiber varieties are also increasing. According to the shape of the division: Flat steel fiber, pressure prismatic steel fiber, waveform steel fiber, bending hook shaped steel fiber, big head shaped steel fiber, double pointed steel fiber, cluster of steel fiber and so on. 2 according to the section shape: Round, rectangular, groove type, irregular 3 according to the production process: Cut off the steel fiber (cut off with a fine steel wire); Shear steel fiber (with a thin steel sheet, strip shear); Milling steel fiber (steel or steel ingot cutting); Molten steel fiber (molten steel pumping). The most promising is the dissolution of steel fiber, the lowest price 4 according to the material is divided into: Plain carbon fiber (tensile strength is generally in 300~2500mpa); Stainless steel fiber (according to the material 304310330430446, etc.); Other metal fibers (aluminum, copper, titanium and alloy). According to the state of surface coating: No coating, surface coating of epoxy resin, zinc, etc.. The industrial use of a large number of ordinary steel fiber without coating.

Steel fiber refers to the short steel fiber, cutting the wire, and hook on both ends of the style compressed into in accordance with the relevant provisions, has certain strength.Steel fiber is mainly used in the manufacture of steel fiber reinforced concrete and application in the tunnel, industrial floor, etc.446 # steel fiber is a kind of brand, starting with four words, apart from 446, with four words beginning with 430;all begin with four words of steel fiber, is a stainless steel fiber, because they have a common characteristic, is containing chromium (cr). Steel fiber with corrosion resistant metals: chromium (cr), because of strong corrosion resistance of cr, so widely used in metallurgical industry, refractory material industry and chemical industry.Specific point is widely steel mills, used by metallurgical plant and chemical plant.Steel mill of steel water tank, for example, electrodes, metallurgy factory of furnace wall, furnace door, roof block, etc. After the stainless steel fiber mixed with refractory matrix, can greatly improve the heat resistant structure thermal cycle impact resistance, heat resistance and abrasion resistance performance of the grade, can extend the service life of refractory material and industrial furnaces several times to dozens times, prevent or reduce high temperature crack, improve the bending strength, improve the snap heat and cold resistance and improve the coefficient of thermal conductivity, so as to improve the work efficiency, reduce production costs.
Weathering steel is a series of low alloy steels between normal steel and stainless steel, carbon steel adds a small amount of copper, nickel and other corrosion-resistant elements, and tough, plastic with stainless steel rolling, forming, welding and cutting, abrasion, high temperature, fatigue resistance properties; weather resistance for carbon steel 2~8 double coating for carbon steel 1.5~10 times. Mainly used in railway cars, bridges, towers and other long-term use of steel exposed to the atmosphere. http://www.sellsteels.com/steel-plate/A588M.html
