Stainless stee
Stainless stee& Ge; about 40 thickness: cold rolled 2B plate (0.09 & mdash; 0mm); hot rolled industrial plate No.1 (3-50mm) medium plate, chemical plate and high temperature plate; width: 5mm --- 850mm steel strip; 1000, 1211250,Plate embossed stainless steel, 1500 1800 and 2000mm coil plate and flat plate surface: 2B smooth surface, No.1 industrial surface, 8K mirror, 9K mirror, wire drawing surface and frosted surface.
The corrosion resistance of duplex stainless steel, which is widely used in many media, is better than that of ordinary l austenitic stainless steel, while super duplex stainless steel has very high corrosion resistance. In some media, such as acetic acid and formic acid, it can even replace high alloy austenitic stainless steel and even corrosion resistant alloy.
.AUSTENITIC FERRITIC duplex stainless steel. It has the advantages of both austenitic and ferritic stainless steel, and has superplasticity. Martensitic stainless steel. High strength, but poor plasticity and weldability.
SPCDSPCD—& mdash; Cold rolled carbon steel sheet and strip for stamping, equivalent to China 08Al (1323) high quality carbon structural steel.
.The difference between duplex stainless steel plate and ferritic 410 stainless steel plate: the comprehensive mechanical properties are better than ferritic stainless steel, especially the plastic toughness, which is not as brittle as ferritic stainless steel.
It has lower linear coefficient than austenitic stainless steel and is close to carbon steel. It is suitable for connection with carbon steel and has important engineering significance, such as the production of composite plate or lining.
The length of tungsten electrode protruding from the gas nozzle is preferably 4 ~ 5mm. In places with poor shielding such as fillet welding it is 2 ~ 3mm, and in places with deep groove it is 5 ~ 6mm. The distance from the nozzle to the working is generally no more than 5mm.
410— Martensite (high strength chromium steel), good wear resistance and poor corrosion resistance.
Hardness stainless steel pipes are usually measured by Brinell,Quotation for 2205 stainless steel plate, Rockwell and Vickers hardness indexes.
In order to obtain seamless pipes with smaller size and better quality, cold rolling, cold drawing or a combination of both must be used. Cold rolling is usually carried out on a two high mill. The steel pipe is rolled in an annular pass composed of variable section circular groove and fixed conical plug. Cold drawing is usually carried out on a single chain or double chain cold drawing machine of 0.5 ~ 100t.
technological innovation.Stainless hot plate (grade I) GB4239-91 stainless cold strip (grade I)
The cold rolled steel strip has good strength and yield ratio, and the hot rolled steel strip has good ductility and toughness.
This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (slotted pipe). According to different manufacturing processes, it can be divided into several basic types: hot rolling, cold drawing and cold rolling. According to the section shape, it can be divided into circular pipe and special-shaped pipe. Circular steel pipe is widely used, but there are also some square, rectangular, semicircular,3cr13mo stainless steel plate, hexagonal, equilateral triangle Octagonal and other special-shaped stainless steel pipes.
With the development of social economy, the application of stainless steel pipe has been more and more popular. It will bring new changes in various fields.
Workshop cost.L is a model of stainless steel pipe, and its current use value and market demand are also very large. People who often pay attention to the price of stainless steel pipes will find that the price of stainless steel pipes fluctuates greatly, sometimes rising to an exaggerated degree, and sometimes falling to the bottom. Only after understanding the factors affecting the price of stainless steel pipe can we be keenly aware of the fluctuation of stainless steel pipe price and respond in advance. So what is the price of L steel pipe?
When the stainless steel pipe with solid core welding wire is prefabricated, the welded junction can usually be rotated for welding, and the ventilation is very easy. At this time, the blocking plate is usually used to block both sides of the welded junction in the pipe, and the outside is blocked with adhesive cloth.
Low temperature processing --- martensitic stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote the quenching of martensite. It is suitable for stainless steel which is easy to produce retained austenite.
.Let PS be the external force at the yield point s and fo be the cross-sectional area of the sample, then the yield point & sigma; S = PS / fo (MPA), MPa is called MPa, equal to n (Newton) / mm (MPA = 106pa, PA: Pascal = n / M
Cold rolled oriented silicon steel strip consists of nominal thickness (expanded by 100 times) + code G: ordinary material, P: high oriented material + guaranteed iron loss value (the value after expanding the iron loss value when the frequency is 50Hz and the large magnetic flux density is 7T by 100 times). For example, electroplated tin sheet and steel strip, also known as tinplate. The surface of the steel plate (belt) is plated with tin, which has good corrosion resistance. In addition, it can be used as packaging material for cans, inner and outer sheath of cables, instrument and telecommunication parts, flashlight and other hardware.
