D397
D397 is a CrMnMo-type hot forging die surfacing welding electrode with low-hydrogen sodium coating, which adopts DCEP connection method. The surfacing layer contains martensite+retained austenite, which is resistant to intermetallic wear and abrasive wear.
The product is applicable for hot forging dies with cast steel or forged steel as blank and surfacing welding of high-strength wear-resistant parts, such as steel forging dies of 5CrMnMo, 5CrNiMo and 5CrNiSiW.

1. The welding electrode should be baked at about 300-350℃ for 1h before welding.
2. The work piece should be preheated to above 250℃ before welding, and cooled slowly after welding.

What you cover in your shipping policy and how you communicate it will be highly dependent on your current business operations and supply chain. The goal is to be transparent with customers.
As 2020 brings unforeseen shipping delays and increased carrier costs, it's more important than ever to keep your shipping policy up to date with the following key points in mind:
- Essential shipping details are easy to find. While it is common practice to keep a link to your shipping policy page in the footer of your website, consider how you can also surface important shipping details in the right place at the right time (e.g. on your product page or website banner).
- Clear and concise presentation. Don’t make customers comb through your shipping policy page for the information they need. Whenever possible, make it easy to navigate with clear subheadings, tables, bolded text, and links to learn more.
- Order processing times. After an order is placed, how many days will it take to get it ready to ship? It’s worth communicating if you’re excluding weekends and/or holidays, and if you have certain cutoff times for processing orders (e.g. orders received after 5pm will be processed the next business day). If changes occur within your supply chain, due to peak periods or as a result of COVID-19, you should update your processing times to reflect it.
- Domestic and international shipping options. What are the qualifying regions for your domestic shipping options? International shipping can be broken down in its own section where you list the countries you ship to and estimated delivery timelines. If you offer several shipping options, you can list them in a table so the information is easy to scan. Shipping costs. Break down your shipping costs for the customer. If you have a free shipping threshold, you can communicate in various places as an incentive for customers. Any potential surprise fees should be surfaced too, such as duties and taxes the customer may incur.
