What is steel casting?

Steel is a common casting material. It is an alloy consisting of iron and carbon element less than 2%. To achieve excellent mechanical properties, certain chemical elements like silicon, manganese, sulfur and phosphorus are often added in it in a small amount. So products made in steel casting have great mechanical properties. Steel castings are mostly used when iron castings are not available for excellent strength or wear resistance.


Why Choosing Steel Casting?

There are lots of advantages you can find in steel castings. Steel castings have excellent mechanical properties. Their wear resistance and corrosion resistance can also be improved. Besides, steel casting enable products designing more flexible in shapes and dimensions, which other manufacturing methods cannot achieve. Moreover, steel has good weldability, which means steel castings can work well with other metal components.

Based on these remarkable properties, lots of industries use steel castings. The spectrum ranges from traditional industries, like railroad, construction, drilling and mining industries, to automobile and electronics to oil and gas. Steel castings mainly used in these industries are gears, valves, hardware, agricultural wear parts, marine equipment parts, engine cylinder blocker, mining machinery parts, and railroad truck frames, etc.

Benefits of Steel Casting over Steel Forging

  • Better weldability of steel castings

  • More Complex shapes and dimensions

  • Small parts can be casted by steel with a relative low cost.

  • Chemical composition can be better controlled in steel casting.

  • Certain stainless steel castings have better corrosion resistance than equivalent forgings.

Steel Casting Materials

There are three main categories of steel casting materials: stainless steel, alloy steel and carbon steel.

Stainless steel is an alloy with a minimum of 10.5% chromium content by mass. Because of its high corrosion resistance and wear resistance, and its famous aesthetic appearance, stainless steel is commonly used in food machinery, medical and oilfield industry. The common stainless steels in our company are SS304, SS316, PH17-4 and 2205 Duplex Stainless Steel.


Alloy steel has mechanical properties of high strength, high toughness, wear resistance, corrosion resistance, which makes it perfect for casting wear parts for mining and construction industry. The common alloy steels we have used are 42CrMo, 35CrMo, 40CrNiMo, 4130, 4140, 8630, etc. 


Carbon steel is mostly used for castings that will meet strong stress demand. According to their carbon content, carbon steel is divided into three types, low-carbon steel (WC≤0.20%), middle-carbon steel (WC 0.20%-0.50%) and high-carbon steel (WC>0.5-%). The higher the carbon content is, the higher the hardness and strength will be. The common carbon steels we have used are AISI 1010, AISI 1020, AISI 1035, AISI 1045, AISI 1060, etc. We can also pour other melt steels upon your request.
