Mine Mill Liners

1.Material: Cr-Mo Alloy Steel

2.Material Grade: AS 2074 L2A/L2B/L2C
3.Dimensions: as per drawings

4.Application: Mine Mill, SAG mill

5.Mine Mill Liners Special Features:
The material of Mine Mill Liner are low C or high C Cr-Mo Alloy steel,which depends on the  specific working condition of the SAG mill.
The hardness of AS2074 L2B is HB310-HB380.
We can make big size Mine Mill Liners castings with Sodium Silicate Sand Process & Resin Sand Process.
We can supply alloy steel castings with Mine Mill Liner proper heat-treatment process.
We can produce Cr-Mo alloy steel SAG Mill castings as per AS2074 L2B, L2C, GB/T 26651-2011.

Metallographic structure of AS2074 L2B/L2C Steel is Pearlitic.
