Saw Blade Hi Eng Steel Nge Ni? Knife atan A tha em?

Saw blade hi a tlangpuiin high-speed steel (HSS), alloy tool steel, emaw carbide steel emaw hmanga siam a ni a, chu chu a hman dan azirin a ni. High-speed steel saw blade (M2 leh M42 ang chi) ah hian tungsten leh molybdenum ang chi alloying elements a awm a, heat resistance sang tak a pe a, metal cut nan pawh a tha hle. Alloy tool steel saw blade (9CrSi leh Cr12MoV ang chi) te hian heat treatment hmangin hardness sang tak an nei a, thing emaw plastic emaw tan nan an hmang tlangpui. Carbide saw blade (tungsten steel) te hian tungsten carbide hi matrix atan an hmang a, wear resistance tha tak an pe a, precision machining atan an hmang fo thin. Technically chuan saw blade materials hian hardness, toughness leh heat resistance te chu a balance tur a ni. High-speed steel hian a khauhna chu 600℃thlenga temperature-ah a vawng reng a, chu chuan continuous cutting atan a tha hle. Alloy tool steel hian quenching leh tempering hmangin HRC60 aia sang hardness a thleng thei a, mahse a brittle zawk thung. Carbide hian HRA90 hardness a thleng thei a, mahse impact resistance a pe tlem zawk thung. Industry standard-ah chuan metal cutting saw blade atan HRC58-62 leh thing saw blade atan HRC52-56 hardness a tarlang tlangpui. Thil pakhat chu chemte siamna atana ṭha leh ṭhat loh chu thil awmdan bik a innghat a ni. High-speed steel saw blade chu cutting tool-ah an chantir chuan a hardness sang leh heat resistance hian mamawh thenkhat a phuhruk thei a, mahse heat treatment process (brittleness tihtlem nan low-temperature tempering ang chi) chu resharpening leh adjustment a ngai a ni. Alloy tool steel saw blade carbon content tlemte (0.9%-1.3%) nei te chu forging leh quenching hmangin high-performance cutting tools ah siam theih a ni a, mahse stress relief hi ngaihven tur a ni. Carbide saw blade hi a tlangpuiin direct knive atan chuan a brittleness sang avangin a tha lo hle a, special scenario (engraving knife ang chi)-a hman a nih loh chuan. Practical application-ah chuan saw blade convert-naah hian thil lian tak pahnih ngaihtuah tur a awm a: pakhat chu material uniformity a ni (saw blade hi a tam zawk chu coil emaw forging emaw a ni a, chu chuan segregation a nei thei a) a dang chu geometric accuracy a ni (saw blade hi a tlangpuiin a hring a, stacking emaw sandwiching emaw a ngai). A pum puiin, saw blade material thenkhat (high-speed steel leh alloy tool steel ang chi) chu siam danglam hnuah knife-ah siam theih a ni a, mahse professional processing leh heat treatment a ngai a, an performance pawh specialized tool steel angin a tha lo thei bawk.
