Japan's Sumitomo wear plate

High-strength wear-resistant steel plate --- Japan's Sumitomo Metal's flagship product
SUMIHARD-k340/k400/k500
As we all know, has been plagued by industrial sector is a major problem wear. According to statistics, the industrial developed countries, and parts of machinery and equipment wear and tear caused by the economic losses accounted for 4% of national output. Thus, the solution wear and extend the service life of mechanical equipment and components for industrial sector in the design, manufacture and use of machinery and equipment need to consider the most important issue.
Introduced by the company's world-famous steel company - Japan's Sumitomo Metal Industries company's "SUMIHARD-K" series of wear-resistant steel to high strength, high hardness, weldability, easy to bend these features together, wear-resistant steel in the world "trump card." The Company perennial with stock, according to user specific requirements can be pre-futures to satisfy customer needs.
Feature
Significant wear
K500 and K400, respectively, under the same conditions of use than ordinary steel plate with no less than 4 times and 2.5 times the service life.
Use of this steel can greatly extend the service life of machinery and equipment, and can significantly reduce the weight of machinery and equipment and the corresponding costs.

Weldability and machinability
Because of its remarkable machinability, such as anti-cracking and cold bending, but also to improve its applicability from,
Because of its simple welding and processing requirements, and thus can improve production efficiency.

The breadth of products
We do not bear the hardness and size to provide standard products, but also according to customer requests for specific hardness and size of wear-resistant steel to ensure the diverse needs of various customers.

Remarks
As the thickness increases, the middle part of the hardness of steel will be reduced, not in the ultra-high temperature or ultra-low temperatures using this product.

Compared with ordinary steel features K340, there is no less than twice the abrasion resistance
K400 is not less than 2.5 times the wear resistance
K500 is not less than 4 times the wear resistance
