Pretreatment of molten iron: Pretreatment of molten iron to remove impurities and gases in preparation for the subsequent smelting process of A36 steel plates.
Processability: A36 steel plate has good processability and can be processed by turning, milling, drilling, planing, grinding and other mechanical processing. I
A36 steel plate has a series of excellent properties and a wide range of uses, and is one of the most popular products in the steel market. The following are se
50Cr steel is a high-carbon chromium bearing steel, commonly used in the manufacture of mechanical parts and automotive engine parts, etc. To weld 50Cr steel, t
Cr can increase the hardenability of steel, improve the strength and tempering stability of steel, and has excellent mechanical properties. Cr steel should be u
The level of operators is an important factor affecting the quenching and tempering quality of 50Cr steel. At the same time, there are many reasons such as equi
1. Corrosion resistance of A572Gr65 steel plateThe corrosion resistance of A572Gr65 steel plate mainly benefits from the oxide layer on its surface. At normal t
A572Gr65 steel plate is a high-strength low-alloy structural steel with wide application prospects. At present, this material has been widely used in constructi
A572Gr65 steel plate requires hot rolling or controlled rolling state delivery. In order to ensure good low temperature impact toughness, a strict two-stage con
Sulfur often exists in the form of iron sulfide in P355GH steel plate, and distributed in a network at the grain boundaries, thus significantly reducing the tou
It is easy to produce a hardened structure, if the cooling rate of P355GH steel is too fast during welding, and the interlayer brittleness increases, it will le
Steel plate cutting generally refers to the process of mixing industrial gas and oxygen to reach the cutting temperature, melting, blowing slag and dividing the
The main factors affecting the toughness of the weld for AH32 Steel are: the chemical composition of the base metal, the plate thickness, the welding method of
AH32 steel is a special steel plate for marine engineering equipment and ships. The implementation standard of AH32 steel is the special technical conditions of
Similarities
1.AH32 and AH36 are steel plates with a thickness of no more than 150mm for manufacturing ocean-going, coastal and inland navigation ships, fishing
1. Processing technology: This is also one of the factors that cause oxidation of SA192 thick-walled seamless pipes. From the perspective of manufacturing techn
SA192 large-diameter seamless steel pipe is a long steel material with a hollow cross-section and no joints that is processed by rolling or cold drawing with se
After the SA192 seamless steel pipe is welded, the thermal hardness test of the weld should be carried out. The evaluation standard is that the thermal hardness
SA192 seamless steel pipe belongs to hot-rolled and normalized steel, and its main structure is ferrite + pearlite. SA192 seamless steel pipe has high hardness
(1) The high weld seam reinforcement of SA192 seamless steel pipe makes the primary wave flaw detection impossible, and only the triple wave flaw detection can
1. Raw materials
Some SA192 seamless steel pipe factories will choose round steel produced by small steel factories for processing in order to save costs, but t
