When building rail vehicles, during the process of processing, assembling, and welding the components of each part of the car body, due to the existence of stre
S500MC is a thermomechanically rolled weldable fine grain structural steel. "S" means structural steel; "500" means that the yield is greater or equal to 500MPa
Due to the sensitivity of S500MC steel to high temperature, what is the advantage of lowering the rolling temperature for S500MC steel during hot rolling?(1)Red
SS400 and steel SS41 material plate are both structural steel grades used in the Japanese industrial standard JIS G3101. However, there are some differences bet
Steel SS41 is a type of low-carbon steel that is commonly used in the manufacture of various components and structures. It has good weldability and machinabilit
ST52 iron steel is a low-alloy, high-strength structural steel that is commonly used in construction projects. It has a yield strength of 355 MPa and a tensile
(1) Preheating measures are taken before welding to ensure that the preheating temperature of NM500 wear-resistant steel plate is ≥ 200 °C.(2) The NM500
NM500 wear plate has excellent cutting performance. Due to its high hardness, carbide tools and tool coatings are required for cutting to ensure cutting efficie
NM—Steel for wear-resistant use, N--Nai means "resistant", M--Mo means "grinding", they are the first letters of the Chinese pinyin, 400 and 500 are brine
Carbon steel plate ST52 is a high-strength, low-alloy steel plate commonly used in heavy-duty industrial applications. It has excellent mechanical properties su
15CrMo steel is a heat-resistant steel with pearlite structure, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperatur
For the rolling of 15CrMo steel plate, the following standard requirements need to be met:
(1) Deviation requirements for thickness, width and length
The thickn
1. Cracks appear on the surface of 15CrMo steel after carburizing
Reason:
a.The concentration of surface penetration layer for 15CrMo steel is too high.
b.15CrM
The alloy layer of the NM500 steel has high wear resistance, and the service life of the parts after surfacing is relatively long, which will increase by about
·Cutting. Use plasma cutting, carbon arc cutting and grinding wheel saw to cut large-area composite NM500 wear-resistant steel plates into required shape
Impact resistance. The impact resistance of the NM500 wear-resistant plate is very good. In the process of conveying materials, even if there is a very high dro
Quenching can improve the plasticity and toughness of 15CrMo steel and reduce its brittleness, but it often inevitably reduces the strength and hardness of 15Cr
15CrMo steel belongs to pearlitic heat-resistant steel. It is mainly composed of chromium and molybdenum alloying elements. The alloying element chromium can fo
Carburizing is a heat treatment process in which steel is placed in a medium with sufficient carbon potential and heated to an austenite state and kept warm to
Steel plate A285 is a carbon steel plate that is primarily used in low to intermediate tensile strength pressure vessel applications. A285 is known for its good
A285 grade C materi is a carbon steel plate material commonly used in pressure vessel applications. It offers high strength properties at a relatively low cost,
40Cr steel is a high-carbon chromium bearing steel, commonly used in the manufacture of mechanical parts and automotive engine parts, etc. To weld 40Cr steel, t
The weldability of 40Cr alloy steel is poor, and it is not easy to solder at room temperature. Stress annealing should be done immediately after welding of 40Cr
The level of operators is an important factor affecting the quality of 40Cr steel. At the same time, there are many reasons such as equipment, materials and pro
40Cr steel plate is one of the steels widely used in machinery manufacturing industry. After quenching and tempering treatment, it has good comprehensive mechan
