A204 Pressure Vessel Steel Plate
ASTM A204 boiler vessel plate is molybdenum alloy steel plate, mainly suitable for welding boilers and high temperature pressure vessels. According to the molybdenum content, ASTM A204 boiler container plate is divided into 3 grades: A, B, C. The thickness of ASTM A204 boiler vessel plates is limited only by the ability of the chemical composition to meet the specified mechanical property requirements.
A533 Pressure Vessel Steel Plate
ASTM A533 Boiler vessel plates are manganese-molybdenum and manganese-molybdenum-nickel alloy steel plates suitable for welding pressure vessels. Often with quenching and tempering heat treatment, that is, quenching and tempering state supply. ASTM A533 boiler vessel steel is available in five different strength grades: Class A, Class B, Class C, Class D, and Class E. There are three levels of each category: level 1, level 2 and level 3.
EN10025-2 S235/S275/S355 Carbon Steel Coil
EN10025-2 steel coil is a low-alloy high-strength structural steel, which is made of carbon structural steel (Wc = 0.16%~ 0.2%) by adding a small amount of alloying elements. EN10025-2 steel coil has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low cold brittle critical transition temperature.
Galvanized steel coils are covered with a zinc coating to provide corrosion resistance. G40 galvanized steel coil is a galvanized layer name or A653 standard specification specified in the hot-dip coating process galvanized (galvanized) or zinc-iron alloy (galvanized) steel sheet requirements. The G40 protective coating prevents moisture from reaching the steel structure, thereby improving the corrosion resistance of the steel. This can extend the life expectancy of the steel. G40 is the average coat weight and therefore provides moderate protection.
Z120 is the coating name, which means that the coating thickness on both sides is approximately 120g/㎡ or 36g/㎡ (three-point test) and 90g/㎡ (single-point test). Z120 grade galvanized steel coil is coated with zinc to make it more durable. The working principle of the process is to immerse the coiled steel plate in a galvanizing tank filled with molten zinc. Through the continuous galvanizing process of the thin steel sheet, the galvanized coil is obtained. This type of steel has better formability and good paint adhesion in commercial or architectural use. Another method of producing galvanized steel sheet is through a hot-dip plating process. In this method, it is essential that the steel sheet is heat-treated at 500°C immediately after the exit of the can to form the alloy film coating.
The galvanized steel coil Z275 is a double-sided galvanized carbon steel sheet. This is produced by a metal coating process that passes cold rolled coils through a bath filled with molten zinc. This continuous hot-dip plating or also known as electro-galvanizing is the main process that these carbon steel sheets must go through to produce coils and galvanized sheets. The process consists of applying zinc by electrolytic treatment. After the sheet is subjected to this treatment, a layer of zinc is adhered to the base metal through the iron and zinc bonding layer.
