What grade of iron powder should be used for processing special steel? Are there any other elements on the request? How much are they?
- The main special steel carbon structural steel, carbon tool steel, carbon spring steel, alloy spring steel, alloy structural steel, bearing steel, alloy tool steel, alloy tool steel, high-speed tool steel, stainless steel, heat-resistant steel and high-temperature alloy, precision alloy, gold and other electric heating.s
Classification of special steel products
- According to the carbon content of the steel can be divided into low carbon steel (WC = 0.25%), steel (0.25% WC 0.6%) and high carbon steel (wc>0.6%) according to the content of phosphorus and sulfur can be divided into ordinary carbon steel (carbon steel with phosphorus, sulfur, high quality carbon steel (P), low sulfur and high quality (steel) phosphorus, sulfur lower).In general, the higher carbon content in carbon steel, the higher hardness and higher strength, but lower plasticity. This kind of steel is mainly carbon steel to ensure mechanical properties, so the brand reflects its mechanical properties, represented by the Q+ number, "Q" to "yield point bend" word Pinyin prefix, a digital representation of the yield point value, such as Q275 said the yield point is 275MPa. If the grades are marked with letters A, B, C and D, the quality grade of steel is different. The quantity of S and P is reduced, and the quality of steel is improved. If the letter "F" is marked behind the grade, it is "boiling steel". The label "B" is a semi killed steel, and no "F" or "B" is used as a killed steel. For example, Q235-A = F indicates a yield point of 235MPa for grade a rimmed steel, and Q235-c represents a C grade killed steel with a yield point of 235MPa.s
What are the varieties of special steel
- China and Japan, the definition of special steel is relatively close, the special steel into high quality carbon steel, alloy steel, high alloy steel (alloy element is greater than 10%) three categoriess
How can I determine the cooling water flow of square billet mold for special steel?
- Mold heat balance method. If the heat of the molten steel in the mould is taken away from the cooling water, the heat released by the solidification of the molten steel is equal to the amount taken away by the cooling waters

What is the difference between general steel and special steel?
- Pu steel: full name ordinary steel, mostly with plates, profiles and wire form. Ordinary steel is the basic material of the earliest, the largest amount of use in industry, widely used in architectural structure, bridge components, hull structure, transportation, machinery manufacturing, agriculture, textile, defense industry, metal products, food industry, household appliances and other various departments of the national economy.s
Is the steel column of the steel structure HM a special steel?
- Because the legs are parallel inside and outside, the legs are at right angles and are assembled and assembled into components to save welding and riveting, and the work load is 25%. Often used in large capacity requirements, large cross section stability, such as buildings, high-rise buildings, as well as bridges, ships, lifting transport machinery, equipment foundation, support, foundation piles.s
