Welded ASTM 304L Bright Surface Decorative Stainless Steel Tube
Stainless steel decorative tube are also called stainless steel welded pipes for short. Commonly used steel or steel strips are welded into steel pipes after being curled and formed by the machine and the die. Welded steel tube has the advantages of simple production process, high production efficiency, many varieties and specifications, and less equipment, but its general strength is lower than that of seamless steel pipe.
Characteristics of welded steel tube:
From the above process, we can see that: First, the product is continuous on-line production, the thicker the wall thickness, the greater the investment of the unit and the dissolution equipment, the less economical and practical it is. The thinner the wall thickness, the lower the input-output ratio; secondly, the process of the product determines its advantages and disadvantages. Generally, the welded steel pipe has high accuracy, uniform wall thickness, high surface brightness inside and outside stainless steel pipe fittings (the surface brightness of steel pipe determined by the surface grade of steel plate), and can be arbitrarily ruled. Therefore, it embodies its economy and beauty in the application of high precision, medium and low pressure fluids.

Cold Rolled Stainless Steel :
a. Stretch good, toughness, but the price is more expensive;
b. Cold rolling processing surface without oxide skin, good quality;
c. Cold rolling is generally used in the production of strip, the rolling speed is high;
d. Cold rolling than the thickness of the high precision. Mechanical properties, surface and so on in the hot rolling;
e. Cold-rolled due to a certain degree of work hardening, low toughness, but can achieve better yield ratio, used for cold-formed spring and other parts;
f. Cold coil yield point closer to the tensile strength, so the use of risk in the process of no predictability, when the load exceeds the allowable load prone to accidents
g. The surface of the cold rolled steel coil without plating is gray.
h. Cold rolled steel tube surface smoothness is higher than the hot rolled .
