Q:The stainless steel bars how the price difference is, still light sticks according to the size, or the difference between
Followed by specifications and surface treatment, bright rod is polished by surface treatment, the price is relatively high, small diameter to go through many rolling, the price is relatively high.
Q:Is the heating rod good for glass or stainless steel?
There are also good glass, stainless steel is also good, a glass abroad, there are nearly 200.Therefore, choose a good brand is the main, some stainless steel cheap, stainless steel is not used. And the stainless steel is mainly to prevent some large fish zhuangpo, some glass, can solve this problem with a plastic jacket is made of stainless steel, and not enough in the water tank.
Q:201 stainless steel rods rusty, what should I do?
Because the material used for the production of stainless steel bars is generally not very good material.201 stainless steel rods are rusty and are usually surface. As long as the demand is not high, or can be used normally.
Q:How are stainless steel rods made?
Stainless steel bars and other similar material forming method, mainly divided into continuous casting, hot rolling, cold forging and several now casting and rolling, casting alone generally used for pipe, used for machining is hot forging and cold drawing.
Q:What about the weight of stainless steel bars?
For example, the outer diameter of 20mm steel bar, the unit length of 1 meters, weight is 0.02*0.02*3.14/4*1*1000=2.5kg.
Q:Which is good, the moxibustion bar, the stainless steel and the brass?
Whether it is a cylindrical stainless steel or brass contain metal and other materials made, the cylinder bottom pointed flat sleeve, a small tube, a small tube around the hole. Is a kind of warming moxibustion model is applied to provide gas ball Everfount moxa burning will be the formation of oxygen, and air pressure drug to the lesion sites, deep red point through, can be directly carried out on the drug gas heat control, and add the medicine bowl, convenient treatment according to the illness need medication, plus ginger and garlic medicine, cake, enhance the treatment effect, adding poly gas anti burn cover, make the medicine gas in the lesion site, stay together to improve the curative effect, acupuncture, to prevent burns when stopping foreign aggression, moxibustion, burning fire tube automatically extinguished.
Q:How can the stainless steel bar 310 be welded?
Butt welding parts, filler wire for degreasing and oxidation skin. To ensure welding quality.Welding parameters: welding current, tungsten pole diameter, arc length, arc voltage, welding speed, protection air flow, nozzle diameter, etc..(1) welding current is the key factor to decide the formation of weld. Usually determined by the material, thickness, and groove shape of the weldment.(2) the welding pole diameter is decided by the welding current size. The bigger the current is, the bigger the diameter is.(3) arc welding and arc film, the arc length range is about 0.5 to 3mm, and the corresponding arc voltage is 8~10V.(4) welding speed: the current size, welding material sensitivity, welding position and mode of operation should be taken into account when choosing the welding speed.
Q:304 stainless steel bar welding is not firmly what is the reason?
1, check whether the electrode material and the material of parent material are consistent.2, according to the thickness of the weld out the appropriate gap, the current selection to meet the welding process requirements.3, to improve the indoor temperature of welding, or to do corresponding thermal insulation measures after welding.
Q:How about 440C stainless steel?
420 steel than 440C soft, selling point is super rust resistance, good processing, cheap, good toughnessD2 steel is stiffer and has better blade retention than 440C, but it has less toughness and is easier to rust (can only be called semi stainless steel)
Q:304 why are stainless steel bars hard and soft?
Some are hot rolling and some cold rolling, the process is different, annealing also affects soft and hard
