Mechanical machinability in high-speed machine, the feed rate and cutting speed of alloy are the same as L. If carbonization is adopted, the cutting speed is reduced by about 20% compared with L. the performance of machinery and equipment and their components plays a key role here.

Stainless steel pipes are divided into hot rolled, martensitic stainless steel pipes they mainly include semi Ferritic and semi martensitic stainless steel pipes, austenitic stainless steel pipes, austenitic ferritic stainless steel pipes, etc.

.Model 410 & mdash; Martensite (high strength chromium steel), when calculating the approximate weight of stainless steel pipe and multiplying it by the unit price, the price of 6m stainless steel pipe can be roughly obtained, which can be used in the project budget.

L stainless steel pipe is a kind of hollow long round steel, which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, machinery and instruments, etc. In addition, when the bending and torsional strength are the same, the weight is light, so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.

Batch size: a small number of single batch products will affect the unit price.

Model 630 & mdash; Commonly used precipitation hardening stainless steel model, usually also called 17-4; 17%Cr,4%Ni.

Clamping operation the jaw of the caliper must be placed perpendicular to the axis of the pipe and pipe fitting, and the convex ring of the pipe fitting needs to be put into the groove of the jaw for clamping. In order to prevent operation, the operator can only stand on the axis of the pipe, 2b face, (white skin), 2D face, (frosted), HL (wire drawing), 8K face and other surfaces with good quality and brightness.

Stainless steel coil is widely used in chemical industry, food medicine, papermaking, petroleum atomic energy and other industries, as well as various parts of buildings, kitchenware, tableware vehicles and household appliances. 304 stainless steel coil is divided into austenitic stainless steel cold rolled coil and stainless steel hot rolled coil. 304 stainless steel (coil) plate features: beautiful surface and diversified use possibilities; Good corrosion resistance; Longer and more durable than ordinary steel; Good corrosion resistance; High temperature oxidation resistance and high strength, so it can resist fire; Good plasticity and welding performance. It has excellent rust and corrosion resistance, good intergranular corrosion resistance and good processing performance.

1 cold rolled oriented silicon steel strip (sheet) represents: 100 times of DQ + iron loss value (at the frequency of 50Hz, the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of 7T) + 100 times of thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example, dq133 represents cold-rolled oriented silicon steel strip (sheet) with iron loss value of 3 and thickness of 0.3mm. Now the new model is 30q133.

Because the family kitchen and are in the same environment for a long time, the ordinary steel pipe will rust after being used for a period of time, the service life is not long, and it will affect the safety of family drinking water! Therefore, the use of stainless steel pipe here can ensure long-term non rusting, and the corrosion resistance and tensile resistance of stainless steel pipe itself. Professional stainless steel plate, stainless steel coil, stainless steel pipe, safety, environmental protection and economy! The products are exported to foreign countries and are deeply trusted, which makes the stainless steel pipe more and more popular in the field of home decoration!

details.Windproof and ventilation. Where there is wind, please take measures to block the net, and take appropriate ventilation measures indoors.

2. Raw material problem of stainless steel pipe. If the hardness is too low, it is not easy to polish (BQ is not good). If the hardness is too low, orange peel is easy to appear on the surface during deep drawing, which affects BQ performance. BQ with high hardness is relatively good.

The specification and appearance quality shall comply with the provisions of gb14975-2002 stainless steel seamless steel pipe. The steel pipe is usually 5 ~ 10m long (indefinite length) hot rolled steel pipe, and the hot-rolled steel pipe is equal to or greater than 1m. The wall thickness of cold drawn (rolled) steel pipe is 0.5 ~ 0mm, 0 ~ 7m; the wall thickness is greater than 0mm, 5 ~ 8m.

.When transporting domestic and drinking water, the pipeline shall not pass through the toxic pollution area. If necessary, protective measures shall be taken.

300 series & mdash; Chromium nickel austenitic stainless steel.

In polluted air (such as atmosphere containing a large amount of sulfide, carbon oxide and nitrogen oxide), in case of condensed water, acetic acid liquid points will be formed, which will lead to chemical corrosion.
