Product description

304L Stainless steel tubing belongs to the international stainless steel marking method. 304L Stainless Steel tubing--S30403 (U.S. AISI, ASTM) 304L corresponds to the Chinese brand is 00Cr19Ni10, characteristics and uses: lower than the 0Cr19Ni9 carbon content of steel, resistance to intergranular corrosion superior, for welding after the heat treatment components.

 

International Stainless Steel Marking method

The American Iron and Steel Society uses three digits to label various labels.

Quasi-grade malleable. One:

① austenitic stainless steel with 200 and 300 series of digital indicators,

② ferrite and martensitic stainless steel are represented in the 400 series. For example, some of the more common austenitic stainless steels is marked with 201, 304L, 316, and 310,

③ ferritic stainless steel is marked with 430 and 446 and martensitic stainless steel is labeled 410, 420 and 440C

Remember, the dual phase (Austenite-ferrite),

④ stainless steel, precipitated hardened stainless steel and high alloy with iron content below 50% are usually patented or trademark names.


Numbering and Presentation Methods for Steels

① uses the international chemical element symbol and the national symbol to represent the chemical composition, uses the Arabic letter to represent the constituent content:

Such as: China, Russia 12crni3a

② uses fixed digit numbers to denote steel series or numbers, such as: USA, Japan, 300 series, 400 series, 200 lines;

③ uses the Latin alphabet and sequence to form an ordinal, indicating only the purpose.


Chemical Composition(%)

C ≤ 0.03

Ni: 8.00~12.00

Cr: 18.00~20.00

Mn ≤ 2.0

Si ≤ 1.0

S ≤ 0.030

P ≤ 0.035

 

304L Stainless steel tubing 18cr-8ni-Low carbon as low C 304 steel, in general, its corrosion resistance is similar to 304 steel, but after welding or after the elimination of stress, its resistance to intergranular corrosion is excellent, in the case of heat treatment, can also maintain good corrosion resistance, the use of temperature -196℃~800℃. It is used in the field of chemical, coal and petroleum industry, which has high resistance to grain boundary corrosion, and has difficult parts for heat-resisting parts and heat treatment of building materials.


Mechanical Properties

YS(MPA) ≥ 175

TS(MPA) ≥ 480

EL(%)≥ 40

HV ≤ 200


Characteristics

18cr-8ni as a widely used steel, has good corrosion resistance, heat resistance, low-temperature strength and mechanical properties, stamping, bending and other hot processing, no heat treatment hardening phenomenon (non-magnetic, the use of temperature -196℃~800℃).

 

Application

Household products (1, 2 types of tableware, cabinets, indoor pipelines, water heaters, boilers, bathtubs), auto parts (windshield wipers, molded products), medical equipment, building materials, chemicals, food industry, agriculture, marine components;

Stainless steel, Alloy tool steel (in thousands of points C content), such as: 1cr18ni9 1 per thousand (that is, 0.1%c), not rust C ≤0.8% such as 0cr18ni9, ultra-low carbon C ≤0.3% such as 0cr17ni13mo
