Q3: What makes stainless steel stainless?

A3: Stainless steel must contain at least 10.5 % chromium. It is this element that reacts with the oxygen in the air to form a complex chrome-oxide surface layer that is invisible but strong enough to prevent further oxygen from "staining" (rusting) the surface. Higher levels of chromium and the addition of other alloying elements such as nickel and molybdenum enhance this surface layer and improve the corrosion resistance of the stainless material.

Q:The working principle of steel punching machine
Then tell you about the characteristics of mechanical punching machine1 mechanical punching machine uses lever principle, screw rod force, operation, saving labor, punching efficiency is high, punching once only 20-30 seconds;2 the main force head of the mechanical punching machine is made of super high strength alloy steel. It is light in weight and easy to carry;3 mechanical punching machine has the advantages of simple structure, convenient maintenance.
Q:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Really not assured, spend some money to let people count, but as long as there is no special structure or shape, then you do not have to spend the wrong money.
Q:TIG welding of stainless steel plate and steel, how to regulate the argon arc welding
1 current 60-80, air flow 0, 5With 2 plates and square steel welding and 1 identical, square and square steel welding current is available in 120, with stronger welding flow unchanged.30, 2 of the plate welded iron angle iron, it is difficult to weld, the plate is too thin.4, black needle and gun mouth flat, go in a little can also.5 general gas stations are filled with large bottles of change. 13 presses per bottle. 8L only do the spare, easy to carry, only do the skeleton and winding, spot welding, sealing up can do 40 to 50.7 welding galvanized sheet iron with a lot of trouble. Try it and you'll see. The iron steel welding line, is not strong.
Q:The water was poured into the square on how to prevent rust after treatment
Of course, all can be cloth, face sassafras. After the surface has been cleaned, it is better to put rust on the inside and outside surfaces and store them.Then is the steel material after storage should always check, if there is corrosion, corrosion layer should be removed.Finally, the corrosion of the more serious square steel, rust should not be long-term storage, should be used as soon as possible.
Q:What is the hot dip galvanized steel, production process?
Also called hot galvanized and hot dip galvanizing: hot dip galvanizing is an effective way of metal corrosion, mainly used for metal structure on the facilities of the industry.
Q:Hot dip galvanized steel can be welded
Hot dip galvanized steel can be welded. The main methods of welding are as follows:1. manual arc welding. Remove the welding seam and the nearby zinc coating before welding. The welding rod can choose J421/J422/J423 and E5001/E5003 welding rod according to different requirements;2. gas metal arc welding. CO2 gas shielded welding can be used.3. argon arc welding.4. resistance welding.
Q:The difference between galvanized square and galvanized steel
The first dip galvanized pipe is a hot-rolled or cold-rolled galvanized steel or galvanized sheet for the blank shape by the cold bending process after section steel pipe welded square hollow square cross-section shape and size of the high-frequency. Or the cold formed hollow steel pipe prepared in advance will be galvanized by hot-dip galvanizing.
Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:As for steel structure steel, how appropriate
Column: 200*200*8 rectangular tube as column, beam (main beam) is 300*300*12, secondary beam is 150*150*8@1500 evenly distributed. Roof beam 150*150*8 herringbone roof truss.
Q:Twist steel (twisting steel) there is no standard?
Lattice steel plate steel bar is also called twist, the steel twisted shape, so only when the square size annotation annotation, common general specifications for 8*8mm, 6*6mm, 5*5mm, in the standard steel plate, the bar is defined as fixed on the bearing flat steel, round steel, square steel twisted or flat, that is say, don't necessarily use twisted steel (steel twist) but hot dip galvanized steel grid plate used in the steel industry used torsion, stainless steel using round steel, and make use of flat bar made of steel plate. We called steel grid plate or pressure locking steel plate, steel plate of GB also do this cross sectional area:: twisted steel, round steel bar with flat steel, its cross-sectional area of not less than 20 mm.
