Nelson 304 stainless steel coil factoryHow to choose the model

As long as the steel type is selected correctly and maintained properly, stainless steel will not produce corrosion, pitting, corrosion or wear. Stainless steel is also one of the high strength metal materials used in construction. Because stainless steel has good corrosion resistance, it can keep the structural parts in good condition

Austenitic stainless steel can be used to make stainless springs, clocks and clocks, steel ropes in aviation structures, spot welding process and deformation can only be used to increase the tendency of stress corrosion. Causal part &gamma- M transformation to produce ferromagnetism, when in use

Nelson .Hot rolled stainless steel strip / coil production process: 1. Pickling → 2. High temperature rolling → 3. Process → 4. Annealing → 5. Leveling → ⒍ fine cutting → ⒎ packaging → 8. Reach customers.

When water-soluble paper is used to block the ventilation, since the ventilation is from the weld center, the ventilation pipe shall be quickly pulled out at the rear sealing link,Nelson Stainless steel plate stainless steel coil, and the residual argon inside shall be used for protection, so as to quickly finish the bottom and seal the mouth.

.The surface color is more uniform, the reproducibility is good, and the wear resistance and corrosion resistance are significantly improved.

When transporting stainless steel plates, the products shall be fixed in the carriage to prevent the products from colliding with each other or other sharp objects during transportation, resulting in pits on the surface of the plates, which will not only affect the use, but also affect the appearance.

The surface solidified slab continues to be rapidly cooled through the secondary cooling section until the core of the slab is solid and cut by fixed length flame. The whole process of continuous casting slab of stainless steel pipe fittings is completed.

The super main way to prevent stress corrosion of austenitic stainless steel is to add si2~4% and reduce the N content below 0.04% from smelting. In addition, the content of impurities such as P, Bi and as shall be minimized. In addition, A-F dual phase steel can be selected, the temperature creep rate of the stainless steel pipe sample increases, and the steady creep rate at 800 ℃ (65mpa) reaches the maximum value under several test conditions, and creep fracture occurs. The stability of the stainless steel pipe sample under several conditions

Stainless steel pipe is a kind of economical cross-section steel and an important product in the iron and steel industry. It can be widely used in life decoration and industry. Many people in the market use it to make stair handrails, window guards, railings, furniture, etc. There are two common materials, 201 and 304.

Word of mouth recommendation.Flux coated welding wire is used for backing welding, and argon gas is not used inside the weld. The welder is easy and fast to operate, and has the characteristics of low cost. At the same time, it can also well ensure the welding quality (in the capacity expansion and reconstruction project of Urumqi petrochemical, we use this method to weld 28 junctions and repair junctions,

Some familiar welding methods (except gas welding)

Fingerprint treatment process can obtain fingerprint free effect in the treatment of stainless steel mirror plate, wiredrawing plate, frosted plate etched plate, etc., and can improve the anti rust function.

After molten steel casting, stainless steel pipe fittings generally adopt the same vertical vertical bending or arc continuous caster as carbon steel. The refined molten steel is poured into the ladle, the ladle to be poured is transferred to the top of the tundish mouth through the rotary table, and then the molten steel is poured into the tundish through the long nozzle. Tundish steel

Quality risk.Select according to the width. Generally, there are five kinds of width of brushed stainless steel plate: 1000mm,Nelson Professional stainless steel plate, 1219mm, 1500mm, 1800mm and 2000mm. The length can be cut according to needs, design and evaluate the optimal welding process parameters to ensure that the welded joints have good mechanical properties and corrosion resistance. However, it is also found that the phase ratio is not the only standard to evaluate the comprehensive properties of duplex stainless steel welded joints and the microstructure should also be considered

At low temperature, ferritic stainless steel pipe has low temperature brittleness like carbon steel, while austenitic steel does not. Therefore, ferritic or martensitic stainless steels produce low-temperature embrittlement, while austenitic stainless steels or nickel base alloys do not show low-temperature embrittlement. Of ferritic stainless steel pipe（

Nelson .In austenite and then rapidly cooled. Air cooling can be adopted for thin-walled parts, and water cooling is generally adopted.

The telescopic tube is movable.

This material without titanium and niobium has a natural tendency of intergranular corrosion. The intergranular corrosion can be reduced by adding titanium and niobium, followed by stabilization treatment. A high alloy steel that can corrode in air or chemical corrosive medium. Stainless steel has beautiful surface and corrosion resistance
