Characteristics

Excellent Thermal Insulation: SS304 stainless steel pipe has a thermal conductivity only 1/24 that of copper, reducing heat loss and maintaining a more stable water temperature during long-distance hot water transportation.
Strong Corrosion Resistance: Containing 18% chromium and 8% nickel, SS304 stainless steel forms a dense passivation film on its surface, ensuring structural stability in humid and weakly acidic/alkaline environments.
Stable Processing Performance: The material has good ductility, allowing for bending, welding, and drilling without cracking.

Commonly used stainless steel grades and their characteristics

Steel grade	Grade	Characteristics and Uses
100 Series	101	Commonly used stainless steel grades and their characteristics
100 Series	102	General austenitic stainless steel for furniture applications
200 Series	201	Cold-work-hardening austenitic stainless steel
200 Series	202	Common Austenitic Stainless Steel
300 Series	301	High ductility, suitable for products that need to be formed. It can be rapidly hardened during mechanical processing. It has good weldability. Its wear resistance and fatigue strength are superior to 304.
	302	The corrosion resistance is the same as that of 304. However, due to the additional carbon content, its strength is slightly better.
	303	The semi-machinable type 304 steel containing sulfur and phosphorus, with GB designation of Y12Cr18Ni9, is also referred to as A1 in ISO 3506.
	304	The most commonly used traditional 18/8 stainless steel is GB grade 06Cr19Ni10, also known as A2 in ISO 3506. 304L is similar to 304, but it has reduced the content of C to enhance weldability, and its strength is slightly lower than that of 304. 304LN is similar to 304L, but it has added N to achieve higher yield strength and tensile strength than 304L.
	308	When welding 304, use filler metal as the filler material.
	309	It has better temperature resistance than 304. When welding different steel grades, it is sometimes used together with chromium-nickel-iron alloy as filler metal.
	316	It is an improved type of 304, and it is the second most widely used steel grade after 304, which is for food and medical purposes. It contains the element Molybdenum (Mo), and has a higher Ni content. This makes its corrosion resistance and high-temperature strength significantly enhanced, and its high-temperature resistance can reach 1200 - 1300℃. It can prevent point corrosion, crevice corrosion, corrosion in chloride ion environments, seawater and other special forms of corrosion. Therefore, it can be used under harsh conditions.
	321	Similar to 304, the addition of Ti reduces the risk of weld rusting. To resist sensitization during welding, Nb is added to 347.
