The thickness of cold rolled steel strip is ultra-thin and the thickness of hot rolled steel strip is large.

  430— Ferritic stainless steel for decoration, but poor temperature resistance and corrosion resistance.

.When installing and welding the fixed port of stainless steel pipe, it is difficult to vent on the inner side, and some sides are easy to be blocked. In this case, water-soluble paper + blocking plate can be used for blocking. That is, the easy to vent and good side can be blocked with blocking plate, the difficult to vent and bad blocking plate side can be blocked with water-soluble paper and the weld on the outer side can be blocked with adhesive tape (see Table 2) .

Cold rolled steel strip shall be delivered in the state of heat treatment (annealing, normalizing and tempering after normalizing), and shall be delivered smoothly.

.In order to prevent the occurrence of welding pores, the welding parts must be cleaned if there is rust, oil stain, etc.

6 Density 400 & rdquo; Density of series: 93310s, 309S and 316316 density stainless steel coils of 30323042001 are divided into Austenitic, ferrite martensite, duplex (ferrite austenite) stainless steel cold rolled coil and stainless steel hot rolled coil.

Mechanical properties when the steel or sample is stretched, when the stress exceeds the limit, the steel or sample continues to have obvious plastic deformation, which is called yield, and the small stress value when the yield phenomenon occurs is the yield point.

The inventory of stainless steel pipes may be an important factor in market conditions. This is because at this stage, steel inventory has become an important index to investigate and judge the situation of stainless steel pipeline shopping malls, and has become a wind vane to judge the future market trend. What was the stock of stainless steel tubes at that time? It directly affects the air of shopping malls, and then distributes the business behavior of participants in shopping malls

Meet the needs of architects and structural designers.

Oxygen plus gas flame can not cut stainless steel plate because stainless steel is not easy to be oxidized.

The cost is reasonable.Compared with traditional steel,314 stainless steel strip, stainless steel can not only ensure high strength and weight ratio, but also have good plasticity, toughness, formability and weldability. It is the first choice for car frame. Stainless steel with superior performance can create cars with light weight, strong resistance,Quotation sheet of stainless steel pipe, high safety and long service life. Such frames can be recycled and reused. It can not only save costs, but also save resources. And some other auto parts are also made of stainless steel. Stainless steel has a great potential market in the whole automobile industry!

  309— It has better temperature resistance.

The folded stainless steel hot rolled strip is hot rolled into a strip with a thickness of 80mm-00mm and a width of 50mm-1200mm.

investment.The effect of different stabilizers on the stability of ferritic stainless steel during pickling in base solution was studied by means of weight loss curve and scanning electron microscope. The results show that under the experimental conditions, both complex stabilizer HF and adsorption complex stabilizer 5-sulfosalicylic acid can completely remove the oxide layer on the surface of stainless steel The effect of adsorbing complex stabilizer 5-sulfosalicylic acid is obviously better than that of complex stabilizer HF in the stability effect and the flatness of the research results on the properties and microstructure of stainless steel surface s stainless steel pipe after pickling. The deformation behavior at high temperature at 100 ℃ and strain rate of 0.01 ~ 5 s-1. The rheological stress curve is drawn according to the compression experimental data; based on Arrhenius relationship and considering the strain Factor, and the dynamic recrystallization volume fraction model is established based on the s stainless steel pipe equation. The results show that in the process of thermal deformation of s stainless steel pipe, the flow stress corresponding to lower temperature and faster strain rate is also large; the coupling of stress variable factors The correlation coefficient between the rheological stress of the constitutive model s stainless steel tube and the experimental value is 0.986 88, and the average relative error is only 6%. The model can better predict the deformation resistance of L stainless steel during thermal deformation. The dynamic recrystallization behavior of s stainless steel tube is easy to occur under the processing conditions of high temperature and low speed,Stainless steel 304 seamless steel pipe, and its dynamic recrystallization volume fraction and strain change in S shape. The value obtained by the model is consistent with the experimental data The volume fraction of dynamic recrystallization of s stainless steel tube during hot working can be well. Dense palladium membrane was prepared on porous stainless steel substrate with pore size of 5 & mu; m by electroplating and the combination of the two. The palladium membrane on the surface of porous stainless steel was characterized by seeds and XRD. The results show that the pretreatment is completed with 0.1 GL PdCl2 solution A pure palladium film can be prepared by electroless plating of porous stainless steel and electroplating with palladium ammonia solution with palladium content of 17 GL,

Chloride ions exist in the service environment. Chloride ions exist widely, such as salt, sweat, sea breeze, soil, floating rust of iron foam and so on. Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary low carbon steel. Therefore, there are requirements for the service environment of stainless steel, and it is necessary to remove dust frequently and keep it clean and dry. (in this way, we can give him a & ldquo; improper use & rdquo;) there is an example in the United States: an enterprise uses an oak container to contain a solution containing chloride ions. The container has been used for nearly 100 years. The ninetieth generation of the last century plans to replace it. Because the oak material is not modern enough, the container leaks due to corrosion 16 days after it is replaced with stainless steel.

The cold working process performance and cold forming performance are much better than that of ferritic stainless steel.

.For the manual clamping tool, the upper and lower jaw are fixed modules, and the pressure is set to output a constant pressure of 50MPa. The detection standard is to observe the seam of the upper and lower jaw and press it once or twice.

Origin: domestic and imported (Sweden, Japan, Finland, South Korea, South Africa and Taiwan); classified according to the thickness of thin plate (0.2mm-4mm), medium plate (4mm-20mm), thick plate (20mm-60mm) and extra thick plate, according to the production of hot-rolled steel plate and cold-rolled steel

  430— Ferritic stainless steel for decoration, such as automotive accessories. Good formability, but poor temperature resistance and corrosion resistance.
