China Sinter Machine Grate Bars - High-Quality Suppliers and Factory with 2Cr13 and ASTM HI Materials
Advanced Casting Method
We use coated sand shell superposing casting method for casting. This production process can ensure the stability of the internal structure of the grate bar. This technique not only makes the grate bars have beautiful surface but also increase the production efficiency.
Global Export & Development
Our related products mainly export to Japan, Germany, Russia and etc. With strict technique requirements of our long term customers, we never stop researching and developing to increase the products quality and the quality stability and make great success!
Superior Mechanical Properties
Same material & Same Process, our products will have better mechanical property than most other suppliers.
Strict QC & Trustworthy Service
Strict QC system and complete inspection tool is our main power to guarantee the quality. Traceable material certificates and testing reports, reporting production progress timely to customers. We are not only selling products, but also selling our trustworthy services.

Grate Bar Functionality
Grate bar is the main part of sintering machine. The grate bars are intended for holding and transporting the ore mill by forming a trough space with the railing plates on the pallets.
Cr25 High Cr Grate Bars
Variety grate bars with good heat resistant, abrasion resistant and corrosion resistant capability. For Cr25 high Cr grate bars are inoculated with multiple active elements so its toughness increased largely, ak value achieved 8~12J/cm2, inoxidizability also increased 50~80%, shell mould casting, good surface roughness, accurate dimension.
DIN 1.4777 Material Properties
DIN 1.4777 is a high-temperature resistant austenitic stainless steel material. It exhibits good mechanical properties, including high tensile strength, excellent creep resistance, and good fatigue strength. It also demonstrates a high resistance to oxidation and corrosion at elevated temperatures, making it suitable for use in applications such as furnace components, heat treatment equipment, and exhaust systems in automotive and industrial settings.
Frequently Asked Questions
What casting method is used for your grate bars?
We use the coated sand shell superposing casting method. This production process ensures the stability of the internal structure of the grate bar, provides a beautiful surface finish, and increases overall production efficiency.
Where are your grate bar products exported?
Our products are mainly exported to international markets including Japan, Germany, and Russia, meeting the strict technical requirements of our long-term global customers.
What is the primary function of a grate bar?
The grate bar is the main component of a sintering machine. It holds and transports the ore mill by forming a trough space together with the railing plates on the pallets.
What are the advantages of your Cr25 high Cr grate bars?
Our Cr25 high Cr grate bars are inoculated with multiple active elements to significantly increase toughness (ak value of 8~12J/cm2) and improve inoxidizability by 50~80%. They feature shell mould casting, good surface roughness, and accurate dimensions.
What are the characteristics of DIN 1.4777 material?
DIN 1.4777 is a high-temperature resistant austenitic stainless steel. It offers high tensile strength, excellent creep resistance, good fatigue strength, and high resistance to oxidation and corrosion at elevated temperatures.
How do you guarantee the quality of your products?
We implement a strict QC system and use complete inspection tools. Additionally, we provide traceable material certificates, testing reports, and timely production progress updates to our customers.
