- Q:What type of argon arc welding wire is used in 1Cr13 stainless steel?
- Argon arc welding generally uses H0Cr14 or H1Cr13. Sometimes austenitic steel wires are also selected to improve weldability.1Cr13+Q235B belongs to dissimilar steel welding, H0Cr20Ni10 welding wire is usually used.
- Q:TIG welding of stainless steel weld why blue
- Argon arc welding is a welding technique using argon as protective gas when welding stainless steel. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone.
- Q:Stainless steel drawing plate, polishing plate, mirror panels of the three differences
- Stainless steel polishing plate refers to: stainless steel polishing plate refers to the polished stainless steel polished plate through the polishing machine, this kind of polishing board generally brightness is not high, but also can shine out of fuzzy figure.Stainless steel mirror panel refers to: stainless steel mirror panel, double 8K plate, also known as mirror panel, with grinding fluid through the polishing equipment in stainless steel plate polishing, so that the plate brightness as clear as a mirror. Stainless steel mirror panel from K numbers are generally: 6K, 8K, 10K, 12K these. From the coefficient of demand to be divided into: universal grinding, 8K, high Pu 8K, general fine grinding, 8K, fine grinding, 8K, super fine grinding, 8K these are, of course, the higher the better. Uses: mainly used in architectural decoration, elevator decoration, industrial decoration, facilities, decoration and other stainless steel products.
- Q:What does stainless steel wire drawing mean?
- No fingerprint drawing generally refers to drawing the oil mill, because the surface has a layer of oil film so as to dry grinding than the general resistance of fingerprints, now there is a drawing in inorganic film plated with one layer and the steel substrate to form molecules
- Q:Stainless steel seamless pipe should pay attention to what?
- The common thread has three types: metric, imperial, unified system (also called us). The metric system is in millimeters, with a tooth angle of 60 degrees. For example: "M8X1-6H" stands for metric fine thread with a diameter of 8 mm, with a pitch of 1 mm and an internal thread tolerance zone of 6H.
- Q:Is the inner and outer joint of the water pipe good with copper or stainless steel?
- Choose between these two materials. Use stainless steel as well.
- Q:How can the stainless steel plate lock the screws?
- Meaning: the self tapping screw hole without tapping hole, the screw head is different and sharp, the pitch is relatively large, and no dust silk attack a bit like, without tapping directly into the rotation, and this method is usually used for metal plastic.
- Q:What's the difference between stainless steel screws and carbon steel screws?,
- The stainless steel screws are different from carbon steel screws, and the environment is different,Carbon steel corrosion resistance is relatively poor, long time, the bolt will rust dead.
- Q:Which is better, grade 12.9 screw and stainless steel screw?
- Look at the environment used, in the corrosive environment, stainless steel screws, anti-oxidation, corrosion resistance, stainless steel screws a little betterIn the high strength and high impact environment, grade 12.9 is the top grade of screw. It has high hardness and tensile strength. Its Rockwell hardness (HRC) can reach 39-44, and tensile strength can reach 1220N/mm2
- Q:Several ways of drawing stainless steel wire drawing.
- The thread is a circular felt the shaft is provided with a small motor, which is fixed on the desktop, from the angle of about 60 degrees and the edge of the table, also equipped with a carriage fixed plate pressure tea, with a neat polyester film edge straight on the carriage to limit the use of threads competing. Linear movement and rotation of the carriage felt, in the surface of the rotary plate wipe out the width of thread lines consistent.
