What is the difference between alloy steel and SPA-C railway steel

The company is a leading steel production and exporting group in steel materials with advanced production technology, metal-cutting skill, and steel structures engineering projects. We can supply carbon steel plate and sheet, alloy steel plates and structural SPA-C railway steel steel plates. These hot rolled steel plates are sturdy plates having high quality. Their imperviousness to effect and scrapped area, weld capacity, and workability make them a worthy product in a variety of industries.

High strength steel Q345B, GB/T 1591-2008 Q345B steel size and stock (mm): 7*2200*6500, 15*1050*8000, 5.5*3000*3600, 15*2200*3650, 32*1800*0000, 7*1600*6000, 28.5*3240*5700, 43.5*1630*3900, 23*2980*3500, 46*750*11300, 6*1460*6000, 10*2500*10000, 40*1770*3350, 26*1830*3500, 26*1800*2800, 11*2890*2880, 26*1300*11000, 43.5*1600*3900, 14*2000*3100, 11*2800*3250, 36*1100*8650, 23.4*2280*2800.

SPA-C railway steel, 30CrMnSiA steel plate is a kind of low alloy high strength steel with medium carbon, high strength and good weldability. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. After quenching and tempering, 30CrMnSiA steel can be used as grinding wheel shaft, gear and sprocket. 30CrMnSiA steel has good processability, small deformation and good fatigue resistance. 30CrMnSiA steel is usually used for shaft, piston parts, etc. It is used for various special wear-resistant parts of automobiles and airplanes.

Our SPA-C railway steel, hot rolled mild steel sheets offer excellent corrosion resistance property in the server’s environments. The mild steel sheets provide high resistance to nitric and chloride corrosion in sulfide solutions. These SA283 GrC carbon stel plates offer high strength, tensile, yield, mechanical strength, ductility, hardness, toughness, etc. Mild steel sheet is worked very easily in a high-temperature application and show excellent resistance to chloride crossing and cracking stress.

Mechanical Properties A242 steel:
ASTM A242 specification is made for low alloy steel with high strength, it has good atmospheric corrosion resistance, some applications has shown that it has better corrosion resistance than ASTM A36 steel and ASTM A572 Grade 50.
Tensile: 70 ksi min (3/4 and under), 67 ksi min (3/4-1.5) 63 ksi min (over 1.5-4)

The alloy steel plate is among our business scope, and it is one of our main product. If you have any demands or questions about alloy steel plate, such as 34CrMo4 SPA-C railway steel material properties, 42CrMo4 AISI equivalent, 12Cr1MoV equivalent ASTM, 40Cr material specification, 42CrMo hardness, 50CrMo4 chemical composition and so on, please free free to communicate with us. We have professional technical team and sales team, who will give you SPA-C railway steel professional answers and quotation about alloy steel plate in time.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
