Alloy Engineering Steel Bar GB40RH Quenching and Tempering Delivery Condition
AISI 5140 steel also can be called JIS Scr440 and DIN 1.7035 steel. It is one of the alloy steel. And it is one of the most popular steel grades in the productions of the machine. The 5140 steel price is on the medium level and it was easy to processing. After tempering and quenching, the toughness, plasticity and wearing resistance of it will get better. Steel normalizing can make the spheroidizing for the organization of steel get easier. And it will raise the machinability of the semi-finished product with the hardness less than 160HBS. Tempering it at the temperature of 550℃-570℃ which can make it get better mechanical property. And the hardenability of it is higher than S45C steel. You can check 5140 Steel chemical composition and heat treatment as below.
Standard steel GB in China is 40Cr, the German DIN standard material No. 1.17035/1.7045, German standard DIN grade 41Cr4/42Gr4, EN grade 18 British standard, the British standard BS steel 41Cr4, France AFNOR 42C4 France NF steel standard, standard grade of steel 38Cr4/41Cr4, Italy UNI 41Cr4 Belgium NBN steel standard, standard grade of steel 42Cr4, Sweden SS standard grade 2245. The American AISI/SAE/ASTM standard grade 5140, the Japanese JIS standard grade SCr440 (H) /SCr440, the international organization for standardization ISO standard steel 41Cr4.
1. Belong to the ultra-high strength steel
2. High strength and toughness
3. Good hardenability

After hardening and tempering, it can be used to make the fittings for machines with high medium load and speed of work. Such as the automobile knuckle, gear wheel and axis of the machine tools. If it had been quenching and tempering with medium temperature, it will be a great choice for fittings with high load, low impact and good wearing resistance. Such as the gear wheel, lantern ring and etc. And after quenching and low-temperature tempering, the properties will be better than the last one. People usually use it to make the parts with good wearing resistance and handle high load, low impact. And you can see the principal axis, mechanical bolt and etc are made of it.
