Structural carbon steel of ordinary quality VSt3ps

Brand VSt3ps – purpose

Structural carbon steel of ordinary quality VSt3ps is used for the manufacture of parts, non-load-bearing/load-bearing components of welded/prefabricated structures operating at positive temperatures.

Additional information:

1. Sheet/shaped rolled products of category 5 with a cross-section up to 10mm – load-bearing components of welded structures operating under variable loads at temperatures of -40 +4250C.

2. Rolled products with a cross-section of 10–25 mm – load-bearing components of welded structures with guaranteed weldability, operating in the temperature range -40 +4250С.

Application of material

The main characteristics of one of the most popular materials, such as maintaining the strength of the material despite high loads and a wide range of withstandable temperatures, allow the use of 3ps steel in load-bearing structures. Another advantage is the absence of the need to heat the metal before welding and heat treatment after welding.

Thanks to this, St3ps is used in production:

• Rolled sheet metal with a thickness of material within 10 mm, used for the construction of load-bearing structures connected by welding and used under varying influence of weight on elements from 11 to 25 mm in thickness.
• In the manufacture of reinforcement with a smooth profile used in the reinforced concrete industry.
• Production of profile parts for agricultural engineering.
• Production of expanded metal sheets.
• Manufacturing of pipeline parts.
• Production of connecting profiles for pipeline structures designed to operate under temperature conditions from -20 to +200°.
• Production of electric welding pipes.
• Production of the main layer of cladding for products requiring resistance to wear and corrosion.

Electric welded pipes ST3PS GOST

Straight-seam electric-welded steel pipes (GOST 10704-91, 10705-80) Ø 10 – 426 mm:

Electric-welded steel pipes ST3SP are pipes made by forming and electric welding of rolled sheets or strips.

Electric-welded longitudinal steel pipes ST3PS are manufactured by welding a straight joint parallel to the pipe axis. Electric-welded straight-seam carbon steel pipes are used for laying gas pipelines and pipelines with a working pressure of no more than 16 MPa.

ST3PS steel is a semi-quiet structural material of ordinary quality. It is used for the manufacture of load-bearing and secondary structures that are operated at temperatures above 0 degrees. This type is one of the most popular metals; it is produced by the converter and open-hearth methods.

Decoding of St3 stamps

Any brand can be decrypted in accordance with established standards and regulatory documentation. The designation of steel according to GOST allows you to determine the main qualities when deciphering grades. GOST 380 determines the presence of the following types of metal:

It is worth considering that indices must be used for any marking.

Properties of various brands of St3

The brand of material can be deciphered as follows:

1. ST is a designation that indicates the ordinary quality of carbon steel. Let's use St3sp5 as an example.
2. 3 – a number that is the conventional number of the alloy grade. Depending on the carbon concentration, numbers ranging from 0 to 6 can be used.
3. G - in some cases, a similar symbol may be used to designate manganese. A certain type of steel, for example, St3gps, contains 0.8% manganese.
4. Sp is the degree of deoxidation of the material. When considering St3ps5, we can say that the structure is semi-quiet, but at the same time the degree of deoxidation is quite high. The designation “ps” is used for semi-quiet alloys, “kp” - boiling alloys.

St3kp2 is deciphered in a similar way relatively recently. Previously, other standards were used for labeling. In addition, previously the metal was divided into several different groups.
