Rishbin Machinery Metal Slitting Machine is mainly applied to metal plates, and it is a cross-cutting and slitting processing equipment for metal materials. There are also many kinds of common metal materials. Most of the common metal materials can be cut by the slitter
. Below is a brief summary of several common metal materials for everyone:
Stainless steel is a general name for stainless acid-resistant steel that resists the corrosive effects of atmosphere, acids, alkalis, and salts. To achieve the effect of stainless corrosion resistance, chromium (Cr) content of not less than 13%; In addition, nickel (Ni) or molybdenum (Mo) can be added to increase the effect. Due to the different types and amounts of alloys, there are many different types of alloys.
Stainless steel features: good corrosion resistance, good lightness, high strength; certain elasticity; expensive.
Stainless steel material characteristics
1. Ferritic stainless steel: It has high Cr content, good corrosion resistance, and high-temperature oxidation resistance.
2. Austenitic stainless steel: typical grades such as 1Cr18Ni9, 1Cr18Ni9T1, which is characterized by non-magnetic, good corrosion resistance, temperature strength and high-temperature oxidation resistance, good plasticity, impact toughness, and no gap effect, excellent welding performance, thus , widely used. This type of steel generally has low strength and low yield strength, and cannot be strengthened by heat treatment. However, after cold pressing, the tensile strength can be increased and its elasticity can be improved, but its strength obtained by cold drawing at high temperatures can be facilitated. Therefore, it should not be used to withstand high loads.
3. Martensitic stainless steel
Typical examples are 2Cr13, GX-8, which have magnetic properties, excellent shock absorption, good thermal conductivity, high strength and yield limit, and excellent overall mechanical properties after heat treatment. Due to the addition of a large amount of carbon, it needs tempering after welding to eliminate stress and high-temperature cooling to form the 8's type. Therefore, slow down after forging and tempering should be carried out immediately. Mainly used for carrying parts.
SUS 301 elastic stainless steel
SUS 304 stainless steel
10Cr18Ni9, it is an austenitic stainless steel that cannot be hardened by quenching and only eliminates cold hardening and good resistance to corrosion. Quenching cooling must be carried out in water to ensure the best corrosion resistance. When it is below 900°C, there is a stable oxidation resistance. Therefore, it is suitable for welding of various methods. There is a tendency of intergranular corrosion. Parts may suffer grain boundary corrosion damage when they work in corrosive media, water, and steam for a long period of time. After quenching, the steel has high cold-deformation plasticity and good elongation properties, but poor machinability.
1Cr18Ni9, it is a standard 18-8 austenitic stainless steel that can be strengthened after quenching, but at this time it has good corrosion resistance and cold plastic deformation properties. Due to its high plasticity and toughness, poor machinability, it is suitable for various methods of welding. In addition, the carbon content is higher than 0Cr18ni9, the sensitivity to grain boundary corrosion than heat treatment after welding. Generally, it is not suitable for corrosion-resistant welding parts. When air medium below 850 °C, and air below 750 °C, the atmosphere of fuel combustion products is likely to have more stable oxidation resistance.
Cr13Ni4Mn9, it is austenitic stainless heat-resistant steel. Quenching can not be strengthened, the steel in the quenched state of high plasticity, it can be implemented deep calendering and other types of cold stamping. Steel cutting process is poor. While, with spot welding and seam welding, the effect is good. After welding,it must be heat treatment. In the atmosphere, it has high corrosion resistance. It’s easy to produce grain boundary corrosion. Therefore, more than 450 in the corrosive medium is suitable. It has stable oxidation resistance in hot air below 750-800°C.
1Cr13, it is a ferritic-martensitic stainless steel. After quenching and tempering, it can improve the wear resistance, fatigue and corrosion resistance of parts, and can be nitrided and cyanidized. After quenching and polishing, it has sufficient corrosion resistance in wet atmosphere, steam, fresh water, seawater and tap water. It has good stability in nitric acid at room temperature; it has stable oxidation resistance below 750°C. The steel in the annealed state has high plasticity and can be cold-processed such as deep-calendered steel, punching, bending, and crimping. Gas welding and arc welding results were also satisfactory; the machinability was good and the polishing performance was excellent. After forging, the steel need be cooled and should be tempered immediately.
2Cr13, it is a martensitic stainless steel. After quenching and tempering, it can improve wear resistance, corrosion resistance, fatigue performance and corrosion resistance of parts, and can be used for nitriding and cyanidation. The strength and hardness of the steel after quenching and tempering are higher than those of 1Cr13 steel, and the corrosion resistance and heat resistance are slightly lower. It also has stable oxidation resistance in air medium below 700°C. The weldability and annealed condition of the steel is not as good as that of 1Cr13, but it is still satisfactory. The cutting processability is good. The polishing performance is excellent. The steel should be cooled slowly after forging and immediately tempered.
3Cr13, it is a martensitic stainless steel. Used after quenching and tempering, the corrosion resistance and the thermal stability below 700°C are lower than those of 1Cr13 and 2Cr13, but the strength, hardness, hardenability and thermal strength are all higher. Due to poor cold workability and weldability, heat treatment should be performed immediately after welding. After annealing, there is better machinability. After forging, it should be slowly cooled, and it should be immediately tempered.
9Cr18, it belongs to high carbon chromium martensitic stainless steel. After quenching, it has high hardness and wear resistance, and it can resist corrosion to seawater, salt water and other media. Besides, after its annealing, it has good machinability. Due to hardening and stress cracking, it is not suitable for welding. In order to avoid cracking after forging, it must be cooled slowly (preferably in a furnace). In the hot state, the parts are transferred into a 700-725°C furnace for tempering.
