Stainless steel industrial pipe related knowledge information

304L stainless steel industrial pipe: As a low-carbon 304 steel, under normal circumstances, the corrosion resistance is similar to 304, but after welding or after stress relief, its resistance to intergranular corrosion is excellent, and it can also be used without heat treatment. Maintain good corrosion resistance.
304 stainless steel industrial pipe: It has good corrosion resistance, heat resistance, low temperature strength and mechanical properties, good hot workability such as stamping and bending, and no heat treatment hardening phenomenon. Uses: tableware, cabinets, boilers, auto parts, medical equipment, building materials, food industry (use temperature -196 ° C -700 ° C)
The main features of 310 stainless steel industrial pipe are: high temperature resistance, generally used in boilers, automobile exhaust pipes. Other properties are general.
303 stainless steel industrial pipe: It is easier to cut than 304 by adding a small amount of sulfur and phosphorus. Other properties are similar to those of 304.
302 stainless steel industrial pipe: 302 stainless steel rod is widely used in auto parts, aviation, aerospace hardware tools, chemical industry. The details are as follows: crafts, bearings, sliding flowers, medical equipment, electrical appliances, etc. Characteristics: 302 stainless steel ball belongs to austenitic steel, which is close to 304, but the hardness of 302 is higher, HRC ≤ 28, with good rust and corrosion resistance.
301 stainless steel industrial pipe: good ductility, used for molding products. It can also be hardened by mechanical processing. Good weldability. Wear resistance and fatigue strength are better than 304 stainless steel.
202 stainless steel industrial pipe: belonging to chrome-nickel-manganese austenitic stainless steel, the performance is better than 201 stainless steel
201 stainless steel industrial pipe: belonging to chrome-nickel-manganese austenitic stainless steel, low magnetic
410 stainless steel industrial pipe: belonging to martensite (high-strength chrome steel), good wear resistance and poor corrosion resistance.
420 stainless steel industrial pipe: "cutting grade" martensitic steel, similar to the first stainless steel of Brinell high chromium steel. Also used for surgical knives, it can be done very brightly.
430 stainless steel industrial pipe: ferritic stainless steel, decorative, for example for automotive accessories. Good formability, but poor temperature and corrosion resistance


Grow Light 800W

This 800W Grow Light is a great replacement for hps grow light with full spectrum, can more effectively promote the growth and development of plants. The lights are with dimming function, allowing growers to adjust light intensity according to the plant's growth cycle. And it's with RJ port, can be connected by smart controller, and controlled by it. If with controller, we can adjust lighting intensity, stimulate sunrise and sunset, and also control temperature and humidity to make the plant better adapted to different environments. The controller is sold separately. Welcome to contact us for more details.
