1.304 square tube in specification
304 stainless steel square tube in the market at present the existing mold specification is 3mm*3mm-- 300mm*300mm, wall thickness of 0.3mm-- 10mm.
Stainless steel square pipe and round pipe are expressed with caliber, like round pipe 19 is to point to the diameter of 19 mm pipe, 19 mm can also be said to be the caliber of pipe. In the case of a square pipe, a 50 *25 is a rectangular pipe diameter where it's 50 *25mm. Common specifications include 18,19,22,20,38,25,47,60,51,63,79 equal round tubes, 19*19, 38* 25,25 * 25,38 * 38,38 * 25,50 *50 equal square rectangular tubes.
In 2022, the total amount of Chinese steel imported into the Philippine market will be 3.9 million tons, and stainless steel square pipes will only account for 2.5%, or about 97,500 tons.
We export high-quality stainless steel square pipes to the Philippines, and the specifications are very complete. If you have special square tube specifications, please contact our experts.
2.304 square tube again for use
In the Philippines, the steel market has a large demand for stainless steel square tubes. This has a lot to do with the wide range of stainless steel square tubes. Let's talk about its main uses.
(1) Stainless steel square tubes in the field of decoration
Because 304 stainless steel tube has high tensile strength, good inner cavity smoothness and wear resistance, has been widely used in the field of decoration. As the common stainless steel staircase guardrail at home, stainless steel protective Windows, stainless steel doors, stainless steel tables and chairs, etc. They are made of 304 stainless steel decorative control. Many 304 stainless steel pipe manufacturers have also developed many 304 stainless steel decorative pipe design, model specifications, for many customers to choose. This 304 stainless steel tube is a favorite decorative material.
(2) Stainless steel square tubes in the food field
304 stainless steel pipe is used in the field of food, 304 stainless steel faucet is the best accessories in the direct domestic water transmission pipeline. Stainless steel pipe seepage rate is low, can save valuable water. In addition, 304 stainless steel tap water pipe compared with copper tap water pipe, has better water solubility, in high flow conditions will not be corroded. Its insulation performance is also 24 times that of air conditioning copper pipe.
(3) Stainless steel square tubes in industrial production
304 stainless steel pipe is mainly used in crude oil, chemical, medical, food, light industry, machinery equipment instrumentation and other industrial production, transportation pipeline and mechanical system, stainless steel pipe has a wide range of uses. In addition, 304 stainless steel pipe in the case of plate bending and torsional strength is the same, the net weight is relatively light, so it is widely used in the manufacture of mechanical parts and engineering structures. Stainless steel tubes are also often used to make automobile structures and exhaust pipes, and are often used to make various strategic weapons, gun barrels and guns.
3.Advantages of 304 stainless steel tube
(1)long service life
304 stainless steel pipe surface chrome-rich oxide film, has good corrosion resistance in water, so with the economic improvement, people slowly use stainless steel pipe to do stainless steel water pipe.
(2) material health
304 stainless steel tube wall is smooth, not easy to accumulate impurities, not easy to nourish bacteria.
(3) material energy saving and environmental protection
304 stainless steel tube can be recycled, reduce the pressure on the environment.
4.How to distinguish the true and false 304 stainless steel
(1)Through the stainless steel detection agent to test 304 stainless steel true and false, different stainless steel products meet stainless steel detection agent will show different colors, so through different colors to distinguish 304 stainless steel is true, this is also more accurate and standard practice.
(2)The use of magnetic to determine whether 304 stainless steel is true, 304 stainless steel is weak magnetic, so using a magnet to attract magnetic 304 stainless steel will show magnetic is not strong.
(3)With copper sulfate to detect, with copper sulfate wipe to remove the oxide layer of steel, such as not discoloration after wiping, generally can judge stainless steel, but if it becomes purple, if there is no magnetic high manganese steel, magnetic is generally ordinary steel or low alloy steel.
5.304 and 316 stainless steel difference
(1) The main components of metals are different
The chromium content of 304 stainless steel and 316 stainless steel is about 16-18%, but the average nickel content of 304 stainless steel is 9%, while the average nickel content of 316 stainless steel is 12%. Nickel in metal materials can improve high temperature durability, improve mechanical properties, improve oxidation resistance.
(2) material performance difference
304 (0Cr18Ni9) stainless steel is austenitic stainless steel, can not be strengthened by heat treatment, can not be quenched like carbon steel, there is no magnetic. 304 all kinds of mechanical properties are relatively excellent, with considerable corrosion resistance, high temperature resistance, as the most widely used stainless heat resistant steel.
(3)316 (0Cr17Ni12Mo2) stainless steel is after 304, the second most widely used steel, the main characteristics of acid and alkali resistance, high temperature resistance than 304 strong, mainly used in food industry and surgical equipment, and 316 stainless steel also has a remarkable characteristic, is basically no thermal expansion and contraction phenomenon, This is extremely important for precision parts.
6.Price of 304 square tube in Philippines
The price of 304 stainless steel pipe is based on the customer's size, quantity, payment method and other comprehensive pricing. Generally speaking, the greater the quantity, the better the offer. For example, the specification is 38mm*20mm*1mm*6400mm, the quantity of 500 pieces, the price is about $15 per piec.
Because the price of stainless steel has been fluctuating, the price of stainless steel pipe in 2022 will be about US$2000-3000/ton in the Philippines.
Of course, the price is fluctuating with the market, welcome to consult!
