St37-2 steel German DIN standard low carbon steel
St37-2 steel the chemical composition is as follows:
C 0.17-0.20
Mn <1.4
P and S <0.045
Si does not specify
St37-2 steel this material corresponds to our country, equivalent to carbon structural steel Q235B (old name is: A3-B)
Another: because this kind of steel and our country quality carbon structural steel 20 steel similar, also can use 20 steel instead.
ST37-2 steel is an ordinary structural steel used in construction and underground engineering.
ST37-2 steel delivery status: hot rolling, rolling or normalizing.
ST37-2 steel technical conditions: the chemical composition and mechanical properties of Benxi Steel are briefly listed below. When ordering, additional impact, flaw detection, Z direction and component control can be added, and performance requirements exceed standard.
ST37-2 steel chemical composition:
Elements: C: 0.21-0.25, N: 0.009, P: 0.065, S: 0.065
ST37-2 steel mechanical properties: ST37-2 tensile strength 340-470Mpa, ST37-2 steel yield strength 235Mpa, impact energy +20 degrees, 27J minimum.
St37 steel is a German brand, but St37 steel is a general designation, there are a few small numbers. Such as: St37-2, St37-3U, St37-3n, RSt-2, USt37-2 and so on. ST37-2 is a kind of carbon structural steel material in Germany. This material corresponds to our country, equivalent to carbon structural steel Q235B (old name is: A3-B).
ST37-2 steel ordinary carbon structural steel, also known as plain carbon steel. Carbon content of 0.06-0.22%, less than 0.25% is the most common. Of low carbon steel, each of which indicates the minimum yield point of the steel at a thickness of less than 16mm. Compared with high quality carbon steel, carbon content, range of performance, and content of phosphorus, sulfur and other residual elements are wider. China and some countries according to the guarantee of delivery conditions, ST37-2 steel the ordinary carbon steel is divided into three categories: a steel (a steel), only ensure the mechanical properties, does not guarantee the chemical composition, type B steel (B steel), only to ensure that the chemical composition, does not guarantee the mechanical properties; special steel (C steel). Not only guarantee the chemical composition, mechanical properties and guarantee. Special steel is often used to make more important structural parts.
ST37-2 steel the carbon structural steel is mainly used to make engineering structural parts. It is generally used in the supply state, steel sulfur and phosphorus content is higher, allowing 0.050% and 0.045%, respectively. This kind of steel accounts for a large proportion of the total output of steel. This kind of steel is widely used, most of which are welded, riveted or bolted steel structures, and few are used to make all kinds of machine parts. Low strength Q195 and Q215 steel are used for making low carbon steel wire, steel wire mesh, roof plate, welded steel pipe, anchor bolt and rivet etc. Q235 steel has medium strength, good plasticity and toughness, and is easy to form and weld. This kind of steel used for steel and steel structure, also used as rivets, railspike and various mechanical parts, such as bolts, rod, connecting rod etc. Q255 and Q275 steels of higher strength are used for making various agricultural machines, and can also be used as reinforcing steel and railway fish plates.
