speċifikazzjonijiet
D2 Tool Steel is a versatile high-carbon, high-chromium, air-hardening tool steel that is characterized by a relatively high attainable hardness and numerous, large, chromium-rich alloy carbides in the microstructure. These carbides provide good resistance to wear from sliding contact with other metals and abrasive materials. Although other steels with improved toughness or improved wear resistance are available, D2 provides an effective combination of wear resistance and toughness, tool performance, price, and a wide variety of product forms. Also available as an Electro-Slag-Remelted (ESR) product. The remelting process provides improved chemical homogeneity, refinement of carbide size, and the associated improvements in mechanical and fatigue properties.

APPLIKAZZJONIJIET: Rombli, punches, dies għall-blanking, iffurmar, tirqim, u rolling tal-ħajt, skieken shear, skieken għall-ipproċessar tal-ikel, u gauges.

TEMPERATURA KRITIKA :

Ac1: 1449 ° F (788 ℃)

Ac3: 1553 ° F (845 ℃)

AR1: 1418 ° F (769 ℃)

AR3: 1373 ° F (744 ℃)

Sħana minn qabel: To minimize distortion and stresses in large or complex tools use a double preheat. Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1150-1250°F (621-677°C) equalize, then heat to 1400-1450°F (760-788°C). For normal tools, use only the second temperature range as a single preheating treatment.

Awstenitizzanti (Sħana Għolja): Saħħan bil-mod mill-preheat. Forn jew Melħ: 1850-1875 ° F (1010-1024 ° C).

Quenching: Air or pressurized gas to 150-125ºF (66-51ºC). Sizes up to 4 inches (101.6 mm) in thickness will through harden when air cooled from 1575ºF (857ºC). Sizes up to 6 inches (152.4 mm) in thickness will through harden when air cooled from 1625ºF (885ºC).

Ittemprar: Ittempra immedjatament wara t-tifi. Żomm f'temperatura għal siegħa kull pulzier (1 mm) ta 'ħxuna, sagħtejn minimu, imbagħad kessaħ bl-arja għat-temperatura ambjentali. Il-firxa tat-tempra tipika hija 25.4 sa 2ºF (350 sa 400ºC).

Għal reżistenza massima għall-ilbies, ittempra bejn 300-350 ° F (149-177 ° C) għal ebusija ta '62-64 HRC. Għall-aħjar bilanċ bejn reżistenza għall-ilbies u toughness, ittempra bejn 500-550 ° F (260-288 ° C). Dan se jipproduċi 58-60 HRC.

Għal toughness massima, temper doppju, 2 sigħat flimkien ma '2 sigħat, f'temperaturi ogħla minn 950 ° F (510 ° C). Dan se jipproduċi ebusija ta 'inqas minn 58 HRC.

To minimize internal stresses in cross sections greater than 6 inches (152.4 mm) and to improve stability in tools that will be EDM'd after heat treatment, soaking times of 4 to 6 hours at the tempering temperature below 950°F (510°C) are strongly recommended.

Ittemprar: It-ttemprar għandu jsir wara xogħol sħun u qabel ma jerġa' jwebbes. Saħħan b'rata li ma taqbiżx 400 ° F fis-siegħa (222 ° C fis-siegħa) għal 1600-1650 ° F (871-899 ° C), u żomm f'temperatura għal siegħa kull pulzier (1mm) ta 'ħxuna massima; 25.4 sigħat minimu. Imbagħad kessaħ bil-mod bil-forn b'rata li ma taqbiżx 2 ° F fis-siegħa (50 ° C kull siegħa) sa 28 ° F (1000 ° C). Kompli tkessaħ għat-temperatura ambjentali fil-forn jew fl-arja. L-ebusija li tirriżulta għandha tkun massimu ta '538 HBW.
