Q:What does "80 wire" stainless steel plate mean? How much more expensive than the average stainless steel plate?
Stainless steel terminology, the general thickness of C to calculate the negative difference, the 1 C is 0.01MM, so 80C is 0.8MM. 0.8MM thick stainless steel with different thickness, different prices, generally about Yuegui thin.
Q:What stainless steel can be used instead of galvanized sheet?
Galvanized sheet can be replaced by 201 stainless steel.
Q:Inspection method for stainless steel welding
1) measurement, in strict accordance with the requirements of the drawings, and to ensure that within tolerance. Along the column, a top cover, and frame, beam should be straight, without distortion, the straightness (nonstraightness) should meet the requirements on the table diagonal method.2) no distortion, swing, rotation or displacement are allowed in the structures which are completely fixed
Q:What's the difference between 304 stainless steel and 314?
304 is equivalent to 0Cr18Ni9 stainless steel in our country,314 is equivalent to 1Cr25Ni20Si2 stainless steel in our country
Q:What specifications do stainless steel plates have?
General door with 304 doors or rust does not look good they will call you to change at a loss if you can go ah edge thickness wall door frame to plate factory they can count you can also tell them such as simple frame or Rome head of the door is generally
Q:304 how can the water stain on the surface of stainless steel plate be formed?
This is mainly the unclean environment and surface protection measures are not done well, stainless steel plate surface water stains even if frosted, not necessarily can be worn off
Q:430 stainless steel plate maximum temperature tolerance is how many degrees?
All the properties of 430 stainless steel with 430 stainless steel, with good corrosion resistance and better thermal conductivity than austenitic steels, thermal expansion coefficient smaller than the austenitic thermal fatigue, adding stabilizing elements of titanium, parts of the mechanical properties of the welded seam, mainly used for building decoration, household appliances, fuel burner parts, home appliance parts.
Q:How many steps do I need for stamping the stainless steel plate?
Among the world's steel products, 60 to 70% are plates, most of which are finished by pressing. The car body, chassis, fuel tank, radiator plate, boiler drum, container shell, motor, electrical equipment, iron core, silicon steel sheet and so on are all stamping processing. Instruments and meters, household appliances, bicycles, office machinery, household utensils and other products, there are a large number of stamping parts.
Q:Why do galvanized and stainless steel sheets buy more expensive than thin ones?
Feels like you rarely buy stainless steel plates. First of all, galvanized sheet or stainless steel is made of thick hot-rolled billets by cold rolling, so the thickness is generally thinner, and the more processing times, the greater the cost. That's why the thinner is thicker than the expensive one. Once again, the plate has a negative range of thickness, not necessarily all feet thick, and when buying a flat, with suppliers to explain your negative range requirements. If the 1.2MM board gives you 1.0MM, it's a bit too exaggerated.
Q:Lead and stainless steel plate welding together? How do you solder it?
In addition, ultrasonic welding and ultrasonic welding are also a solid phase welding method with mechanical energy as energy source. Ultrasonic welding, welding workpiece in lower static pressure, issued by the sound of very high frequency vibration can make joint surface crack friction and heating to produce strong welding temperature and the formation of the combination. Ultrasonic welding can be used for welding between most metal materials, can realize metal, dissimilar metal and metal and nonmetal welding can be applied to the repetitive production of metal wire, foil or 2~3mm plate metal joint.
