التركيب الكيميائي (وزن٪)

وصف C22.8 is one of the very commonly used plain carbon steels. It has a nominal carbon content of 0.22% with approximately 0.65% manganese. It is a good combination of strength and ductility and may be hardened or carburized. تطبيقات C22.8 steel is typically used for moderate strength structural applications such as cold formed fasteners and bolts. It is often used in the case hardened condition. الخصائص الفيزيائية (قيم أفاراجي) في درجة حرارة الجو المحيط Modulus of elasticity [10³ س N / مم ²]: 210 Density [g/cm³]: 7.84 لينة التليين Heat to 870-980^س C, cool slowly. This will produce a minimum tensile strength of 450 MPa. تخفيف الاجهاد Stress relieving to remove machining stresses should be carried out by heating to approx. 540^س C, holding for 1-2 hours at heat, followed by air cooling. This operation is performed to reduce distortion during heat treatment. تصلب Harden from a temperature of 820-870^س C followed by water quenching. هدأ Tempering temperature: Please ask. تزوير Hot forming temperature: 1050-850^س C.التشغيل في الماكينات Machinability is good at 65% compared to 1112 carbon steel as 100% baseline. المقاومة للتآكل Not corrosion resistant. The steel will rust unless protected. لحام Readily weldable by all of the standard methods. العمل الباردة C22.8 steel is readily cold worked by all conventional methods. A stress relief anneal may be needed after extensive cold work. تنصل The information and data presented herein are typical or average values and are not a guarantee of maximum or minimum values.
