    304&304L Stainless Steel Pipe

    Material Introduction 304 stainless steel,also known as 18/8 stainless steel, European norm 1.4301, is the most common stainless steel. The steel contains both chromium (usually 18%) and nickel (usually 8%) metals as the main non-iron constituents. It is an austenite steel. It is not very electrically or thermally conductive, and is non-magnetic. It has a higher corrosion resistance than regular steel and is widely used because of the ease in which it is formed into various shapes. Grade 304L is the low carbon version of 304. It does not require post-weld annealing and so is extensively used in heavy gauge components Images for your reference Chemical composition Typical compositional ranges for grade 304 stainless steel Grade 304 304l C ≤0.08 ≤0.03 Si ≤1.00 ≤1.00 Mn ≤2.00 ≤2.00 Cr 18.00~20.00 18.00~20.00 N ≤0.10 - P ≤0.045 ≤0.035 S ≤0.03 ≤0.03 Ni 8.00~11.00 8.00~11.00 Mechanical Properties Typical mechanical properties for grade 304 stainless steel Grade 304 304L Tensile Strength (MPa) min 520 480 Yield Strength σ0.2 (MPa) min 205 175 Elongation (δ5 (%)) min 40 40 Hardness (HR B) max 90 90 Hardness (HB) max 187 187 Physical Properties Typical physical properties for grade 304 stainless steel Physical properties for grade 304 stainless steel Grade 304/304L Density (g/cm3) 7.93 Elastic Modulus (GPa) 194 Mean Coefficient of Thermal Expansion (μm/m/°C)0-100°C 17.3 Thermal Conductivity (W/m.K) at 100°C 16.3 at 500°C 21.5 Specific Heat 0-100°C (J/g.°C) 0.5 Electrical Resistivity (20℃,10-6Ω•m) 0.73 Range of Application System Description: 304 stainless steel is the most widely used as a chromium - nickel stainless steel, as a widely used steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; stamping, bending and other thermal processing, and no heat treatment hardening (temperature -196 ℃ ~ 800 ℃). Corrosion in the atmosphere, industrial atmosphere or if it is heavily contaminated areas, the need for timely clean to avoid corrosion. Suitable for use in food processing, storage and transport. It has good processing properties and weldability. Plate heat exchanger, bellows, household goods (1,2 tableware, cabinets, indoor pipes, water heaters, boilers, bath), auto parts (windshield wipers, muffler, mold products), medical equipment, building materials, chemical, food industry , agriculture, ship parts, millet mobile phones. 304 stainless steel is a nationally recognized food-grade stainless steel. Typical applications include: Food processing equipment, particularly in beer brewing, milk processing & wine making. Kitchen benches, sinks, troughs, equipment and appliances Architectural panelling, railings & trim Chemical containers, including for transport Heat Exchangers
