253MA Plate Mechanical waiwai

ʻO 253MA Plate Corrosion kū'ē a me ka hoʻohana kumu nui:

1.Corrosion Resistance: 253MA kaena maikaʻi oxidation kū'ē, kiʻekiʻe-mahana corrosion kū'ē, a kupaianaha kiʻekiʻe-mehana ikaika mechanical. ʻOi aku ka maikaʻi i loko o ka pae wela o 850 a 1100 ° C.

2. Temperature Range: No ka hana maikaʻi loa, ʻoi aku ka maikaʻi o 253MA no ka hoʻohana ʻana i loko o ka pae wela o 850 a 1100 ° C. Ma nā mahana ma waena o 600 a me 850 ° C, hiki ke hoʻololi i ke kūkulu ʻana, e alakaʻi ana i ka hoʻohaʻahaʻa ʻana i ka paʻakikī i ka lumi wela.

3.Mechanical Strength: Uaʻoi aku kēia'āpana i nā mea kila kila maʻamau, e like me 304 a me 310S, ma keʻano o ka ikaika tensile no ka wā pōkole ma nā mahana likeʻole ma luna o 20%.

4.Chemical Composition: 253MA nā hiʻohiʻona i kahi hui kemika kaulike e hāʻawi iā ia i ka hana ʻokoʻa ma ka pae wela o 850-1100 ° C. Hōʻike ʻo ia i ke kūpaʻa hoʻoneʻe kiʻekiʻe loa, me ka pale ʻana i nā mahana a hiki i 1150 ° C. Hāʻawi pū ʻo ia i ke kūpaʻa creep maikaʻi a me ka ikaika fracture creep.

5.Corrosion Resistance: Ma waho aʻe o kona mau mea wela kiʻekiʻe, hōʻikeʻo 253MA i ke kū'ē maikaʻi loa i ka wela wela a me ka'ōpala palahū ma ka hapanui o nā kinoea.

6.Strength: Loaʻa iā ia ka ikaika kiʻekiʻe a me ka ikaika tensile ma nā mahana kiʻekiʻe.

7.Formability a Weldability: Uaʻikeʻiaʻo 253MA no kona kūlana maikaʻi, weldability, a me ka machinability.
