Q:310 stainless steel resistance to high temperature?
Features: suitable for making all kinds of furnace components, with a maximum temperature of 1200 degrees, continuous use temperature of 1150 degrees CelsiusUses: furnace materials, materials for automotive cleaning equipment
Q:What's lined with stainless steel?
Trenchless stainless steel lining construction method can be widely used in water supply, drainage, gas, heat, telecommunications, electricity, industry and other pipelines. Stainless steel lining pipe, high temperature resistance, can transport hot water, boiling water, steam, and safety and health. The installation of stainless steel tube after the whole bearing pipe resistance, impact resistance, corrosion resistance and other properties to strengthen and enhance the original tube, not only can be used for civilian water and gas, can also be used for fluid transportation industry.
Q:Why is stainless steel magnetic?
There are kinds of stainless steel at room temperature, the organizational structure can be divided into several categories: 1. austenitic: such as 304, 321, 316, 310; 2. martensite or ferrite, such as 430, 420, 410; austenitic is non-magnetic or weak magnetic properties, martensite or ferrite is magnetic. Usually used as a decorative stainless steel pipe,Most of the stainless steel plate is Austenitic 304 stainless steel material, is generally non-magnetic or weakly magnetic, but fluctuations in chemical composition caused by smelting or processing of different magnetic properties may also appear, but this can not be considered to be counterfeit or substandard, what is the reason? The above mentioned austenite is non-magnetic or weakly magnetic, and martensite or ferrite is magnetic, due to melting segregation or improper heat treatment, will cause a small amount of martensite Austenitic 304 stainless steel body or ferrite.
Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 is a stainless steel number, 2.9 refers to the pipe wall thickness.
Q:304 stainless steel seamless tube weight how to calculate?
The common marking methods in the market are 00Cr19Ni10, SUS304, in which 00Cr19Ni10 is generally used to indicate standard production of the national standard. Generally speaking, ASTM standard production is indicated, and SUS 304 represents standard production.
Q:In stainless steel tubes, why are there some SS in the back and some standard L, such as 316L and 316SS? What's the difference?
316: corresponding to China's brand 0Cr17Ni12Mo2316L: corresponding to Chinese brand 00Cr17Ni14Mo2316L steel is a low C series of 316 steel grades. It has better corrosion resistance except for the same characteristics as 316 steel.
Q:SA-179 what kind of material is steel pipe?
SA179 corresponds to China's material is GB8163 10# seamless steel pipe.
Q:Is galvanized steel pipe stainless steel pipe?
No, the steel pipe is generally divided into stainless steel pipe, welded steel pipe, spiral steel pipe, low alloy steel pipe and so on.
Q:Under what circumstances can the stainless steel pipe be welded by argon arc, and under what conditions can the arc welding be used?
Argon arc welding is a kind of welding technology using argon gas as protective gas. 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. Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Q:What is the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
