In terms of processing except Has Iron, carbon of Outside, still Add other alloys The materials of elements are generally called Alloy steel. According to the different elements added and the appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic, etc. can be obtained.
In this issue, the editor mainly introduces the alloy steel products of Haoxuan International:
I Product No.: 12Cr1MoV
Product overview:
12Cr1MoV Steel and 12CrMoV Compared with the alloy tube, the alloy tube has higher oxidation resistance and thermal strength. 12Cr1MoV The creep limit of steel is very close to its ultimate strength value, and it has high plasticity under ultimate tension; The steel has good processability and weldability, but it needs to be preheated to 150℃ Above, stress relief treatment is required after welding.
Product advantages:
12Cr1MoV National standard high-performance alloy structural steel, executive standard: GB/T3077-2015 。 12Cr1MoV It has higher oxidation resistance and heat strength. The creep limit of this steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension. The steel has good processability and weldability, but it needs to be preheated to 300℃ Stress relief treatment is required after welding. This kind of steel is mainly used after normalizing and high-temperature tempering to make the working temperature of high-pressure equipment not exceed five hundred and seventy ～ 585℃ Superheated steel pipe, conduit, coil and other corresponding forgings.
Scope of application:
For petroleum, petrochemical, high-pressure boiler, etc., seamless tubes for special purposes include seamless tubes for boilers, seamless tubes for geological purposes, seamless tubes for petroleum, etc.
II Product No.: 15CrMo
Product overview:
15CrMo Steel with pearlite structure and heat-resistant properties exhibits high thermal strength (δ) at high temperatures b ≥ 440MPa ）And oxidation resistance, and has certain hydrogen corrosion resistance. Due to the high content of Cr 、 C Compared with other alloy elements, the hardening tendency of steel is obvious, and the weldability is slightly poor.
Product advantages:
15CrMo A grade of alloy structural steel, belonging to pearlitic heat-resistant steel, which has a carbon content of 0.15% And chromium and molybdenum are added into the steel, where III is the meaning of the third grade forging parts, 15CrMo stay 500-550 The endurance strength below ℃ is high, the workability and cold strain plasticity are good, and the weldability is acceptable (preheat to three hundred ℃, post weld heat treatment). It is generally used in the normalizing and high-temperature tempering state.
Scope of application:
For petroleum, petrochemical, high-pressure boiler, etc., seamless tubes for special purposes include seamless tubes for boilers, seamless tubes for geological purposes, seamless tubes for petroleum, etc.
Whether 12Cr1MoV still 15CrMo For our products, Haoxuan International guarantees that the price is affordable, the quality is worry free, the logistics is fast, and the service is in place. Welcome new and old customers to inquire about the goods!
