Poukisa sèvi ak SAE4340/4140 ba wonn kre olye pou yo ba solid pou zouti perçage?
Ba kre bay pi lejè pwa, pi wo rèd torsional ak pi bon dissipation chalè pandan w ap kenbe gwo fòs.
Ki diferans prensipal ki genyen ant SAE4340 ak SAE4140 ba asye perçage kre?
SAE4340 se yon Ni-Cr-Mo asye alyaj (genyen 1.65-2.0% Ni), pandan y ap SAE4140 se yon asye alyaj Cr{-Mo (pa gen nikèl).
