Steyn has 419 Test wickets to his name.
Dale Steyn has been battling with injuries in recent times. After being ruled out from the Test series against India, Steyn missed the successive Test series against Australia.
Steyn eventually ruled himself out of the IPL as he needs time to regain full fitness. In a bid to retain full fitness, Dale Steyn has signed for Hampshire as he bids to return to fitness following a heel injury that forced him to miss the recent Test series against Australia.
The 34-year-old will join the county in June and train ahead of South Africa's tour of Sri Lanka, which starts in July. The plan is that he will return as the county's overseas player for the final weeks of the season.
During the training stint in June, Steyn will fill in for compatriot Hashim Amla, who will be with Hampshire for the first three months of the season, for a one-day match and a four-day first-class game.
"Dale is one of the best bowlers in the world and is extremely motivated to get going after a frustrating period on the sidelines," said Hampshire director of cricket Giles White.
"It seems a great fit for both parties -- we hope that we can help him get back to his best and we look forward to welcoming him to Hampshire."
Dale Steyn with 419 Test wickets to his name is the second highest wicket-taker in Test cricket after Shaun Pollock who has 421 scalps.
