27SiMn hot rolled steel round bar

27SiMn nduweni kemampuan mesin sing apik lan plastisitas deformasi sing adhem. Njaga kekuatan dhuwur lan nyandhang resistance sak perawatan panas lan kateguhan dhuwur sak quenching banyu. 27SiMn baja iki digunakake digunakake ing automobile, Petroleum, industri kimia, industri kapal, 27SiMn tabung baja sing normal lan tempered, fosfat lenga njero lan njaba, umume digunakake kanggo Manufaktur bagean hot stamping mbutuhake kateguhan dhuwur lan nyandhang resistance, kayata macem-macem bagean hydraulic .
