416 Stainless steel 1.4005（UNS41600）

Co to jest stal nierdzewna 416？

416 is a 400 series martensitic stainless steel that offers the best machinability (85%) of all stainless steel, primarily composed of chromium, manganese, and sulfur. The material complies with the ASTM A582 standard and is equivalent to EN 1.4005 (X12CrS13) and UNS S41600. Its superior machinability comes from its high sulfur content, making it especially suitable for high-speed machining operations. Jednakże, the addition of sulfur also reduces its formability, weldability, and corrosion resistance. Common applications include components such as screws, bolts, and pump shafts, where ease of machining and moderate corrosion resistance are required.

* Annealed properties are typical for Condition A of ASTM A582.
** Hardened and tempered Condition T of ASTM A582 – Brinell hardness is specified range, other properties are typical only.
# Tempering of this steel at temperatures of 400 to 580°C should be avoided due to low impact resistance.

416 Stainless steel 1.4005（UNS41600）Właściwości fizyczne

Odporność na korozję

• Demonstrates corrosion resistance to natural food acids, waste products, basic and neutral salts, natural waters, and most atmospheric conditions
• Less resistant that the austenitic grades of stainless steel and also the 17% chromium ferritic alloys
• High sulfur, free-machining grades like Alloy 416 are unsuitable for marine or other chloride exposure
• Maximum corrosion resistance is achieved in the hardened condition, with a smooth surface finish

Odporność na ciepło

Scaling resistance of grade 416 steels under intermittent conditions can be extended up to 760°C, and up to 675°C under continuous operations. Considering the sustainability of mechanical properties, 416 steels should not be employed at temperatures greater than the standard tempering temperatures.

Obróbka cieplna

• Wyżarzanie: Heat to 815-900°C, followed by slow furnace cooling.
• Hartowanie: Heat to 950-1020°C, then quench in oil or air.
• Tempering: Heat to 205-370°C, then air cool.

Spawalniczy

Stopień 416 steel exhibits poor weldability. Welding can be carried by pre-heating 416 steels to 200 to 300°C, followed by re-hardening, annealing or stress relieving at 650 to 675°C.

Skrawalność

Speeds and feed comparable with those of some of the free machining carbon steels. Good chip breakage. Material heat treated at 200 F and cold drawn will give best results.
