ASTM A312 TP316Ti is a titanium-stabilized austenitic stainless steel seamless pipe, known for excellent corrosion, pitting, and crevice resistance, especially at high temperatures, due to molybdenum

EN 1.4301 / AISI 304 and EN 1.4306 / AISI 304L are both common austenitic stainless steels, both being "18/8" chromium-nickel alloys. The main difference lies in their carbon content: 304L (1.4306/1.4

1.4301 material, also known as 304 stainless steel, is a widely used austenitic stainless steel. Its main properties include a density of approximately 7.9 g/cm³, an elastic modulus of approximately

SS304L and SUS304L are essentially the same type of low-carbon austenitic stainless steel (Type 304L), where "SS" (Stainless Steel) and "SUS" (Stainless Steel Use) simply represent different standards

SS316L and SUS316L are essentially the same material: a low-carbon version of 316 stainless steel, with the "L" signifying lower carbon (max 0.03%) for superior weldability and corrosion resistance, e

SUS420 is significantly harder than SUS430 because it's a martensitic steel that can be heat-treated for high hardness (up to ~50 HRC), while SUS430 is a ferritic steel that is not hardenable by heat

SUS420J2 is a Japanese (JIS) martensitic stainless steel, with its closest equivalents being AISI 420 (USA), UNS S42000, and European EN X30Cr13 (1.4028), offering a balance of hardness, wear resistan

SUS420J1 steel plate is a martensitic stainless steel (similar to AISI 420 steel grade), particularly suitable for applications such as cutlery, pump parts, and tools after hardening and polishing. It

ASTM A268 is the standard for ferritic and martensitic stainless steel tubing for general corrosion/high-temp service, and while TP420 is not a standard grade listed (grades are like TP405, TP410, TP4

SUS631 (also known as 17-7PH) is a precipitation-hardening stainless steel with 16-18% Chromium, 6.5-7.75% Nickel, and 0.75-1.5% Aluminum, offering high strength, hardness, and good corrosion resistan

S17700 material is 17-7 PH (precipitation hardening) stainless steel, a high-strength semi-austenitic alloy that is easily formed in the annealed condition. It possesses excellent mechanical propertie

17‑7PH stainless steel Prices generally fall in the range of ~$1.10 to $6.00 USD/kg depending on form, quantity, and finish — with hot‑rolled plates often nearer $3.65/kg for moderate orders and cold
