Gray iron castings in ASTM A48 Class 20 are intended for general engineering use where tensile strength is a major consideration.The grade is equivalent with grey irn GB/T 9439-1988 HT150, DIN 1691 GG15, JIS G5501 FC15, NFA32-101 Ft.15D, BS1452 Gr.150, ISO/R185 Gr.15 in China and other countries. Chemical Composition:C:3.0～3.6 S:≤0.12 P：<0.15 Mn：0.6～1.0 Si：1.4～2.0Please note that this chemical composition is not standard, just from working experience of our iron casting foundry. Mechanical propertiesASTM A48 Class 20 gray iron has a minimum tensile strength of 20,000 psi (140 MPa). Class 20 has a high carbon equivalent and a ferrite matrix. Grey cast iron ASTM 148 Class 20 can be produced by using the following casting process:Sand castingShell mold castingLost foam casting The custom casting components in ASTM A48 Class 20 are these unimportant casting parts with low duty or load, such as boiler parts, covers, wheel, base plate, weight plate, pump body, valve body, pipe fittings, etc
Baoding Guokun can produce and supply various undercarriage parts, sprockets, front and rear idlers, top and bottom rollers, track shoes, pins, heavy duty replacement parts for many compact track loaders and mini-excavators, such as FUWA, SANY, XCMG, HITACHI, IHI, SUMITOMO, LINK BELT, KOBELCO, NISSHA, NIPPON SHARYO, LIEBHEER, MANITOWOC, TEREX DEMAG, TEREX AMERICAN, LIMA, KINKI ISHIKO, Ruston-Bucyrus, etc. Product Name: Forged crawler belt parts, link belt, metal insert(iron core) for rubber track, hot-forged steel inserts, track pad for crawler, steel forging crawler belt parts, forged construction machinery parts, solid steel forged links, solid steel links, steel forged solid links, precision forged and heat treated steel link, etc Metal insert (iron core) for rubber trackRubber track is a conveying system widely used in construction machinery equipments and agricultural machinery.The Metal core attaches itself to the sprocket and prevents the rubber track from slipping off the wheel. Hot Forged Steel InsertsHot-forged steel inserts are used for maximum strength, instead of cast-iron links, like with some aftermarket producers. We supply professionally iron core for rubber track by both forging and precoated sand casting with competitive prices and good services for many years. Mainly export to Japan, Poland, etc. Please mail your inquiry to firstname.lastname@example.org or email@example.com or call us 86-18132789710.
When machining the raw casting parts, some casting defects will be found, such as shrinkage, sand holes, segregation and other various defects, which will cause high reject rate. If melted down, it will take many manual power, material resources and financial resources, etc..So what can be done to reduce some casting defects? High-quality meltingBefore pouring, it is necessary to plan and check all smelting process. As per our customer’s requirements, our engineers will plan and adopt the suitable production plan. Avoid turbulent inclusions and control the flow rate.If using the closed pourcing system or producing the thin-walled casting components, the flow rate of the smelting steel or iron should be increased appropriately, which means that the drop height of metal liquid can not exceed the critical value of the static drop height. Avoid the air bubbles generated by the sand core or sand mold directly entering the liquid. The sand core must maintain a relatively low gas content, and can also be vented to reduce the generation of pores in the sand core. Or the sand core can be completely dried, otherwise the clay or the base sand core mold repair glue is used.
