1.4948 (304H) is a high-carbon austenitic stainless steel suitable for high-temperature environments, while 1.4542 (630/17-4 PH) is a precipitation-hardening martensitic stainless steel with high stre

1.4948 stainless steel (also known as AISI 304H) is a high-carbon, austenitic steel with key elements: Chromium (17-19%), Nickel (8-11%), controlled Carbon (0.04-0.08%), and the balance being Iron (Fe

SUS420J2 is a martensitic stainless steel with high hardness (after heat treatment), lower corrosion resistance, magnetic properties, and good wear resistance, making it an ideal material for manufact

SUS420J2 is a Japanese (JIS) grade of martensitic stainless steel, known for being an affordable, hardened steel with good corrosion resistance, hardness, and wear resistance, often used for tools, kn

ASTM A312 TP316H is a high-carbon (H) grade seamless stainless steel pipe that conforms to the ASTM A312 standard. It is suitable for general corrosive and high-temperature environments and features a

ASTM A312 TP304H refers to austenitic stainless steel tubing (seamless or welded), designed for high-temperature and corrosive environments. It has a higher carbon content (0.04-0.10%) than standard

UNS S30409 is stainless steel tubing made from Type 304H, a modification of standard 304 stainless steel with controlled, higher carbon content (0.04-0.10%) to boost its strength and creep resistance

304H stainless steel (UNS S30409) contains 18–20% chromium, 8–10.5% nickel, and 0.04–0.10% carbon, and exhibits excellent strength retention at high temperatures up to approximately 800°C, making it i

The price of 304 stainless steel is typically between $2.20 and $3.80 per kilogram, while 321 stainless steel (including 321H) is 20% to 40% more expensive than 304 stainless steel, ranging from $3.00

ASTM A36 is a basic carbon steel, great for structural uses but prone to rust, needing coatings outdoors; ASTM 304 is a stainless steel with chromium/nickel, offering superior corrosion resistance, fo
